How to repair peeling roadster rear glass window (suction clamps) DIY guide Audi TT Mk1 Convertible
HTML-код
- Опубликовано: 2 авг 2024
- Apart from the broken engine the next biggest concern is the roadster's rear window glass peeling from the convertible roof. Luckily along with the sale came all of the necessary equipment to complete the job. I cover the major repair of the droptop's delaminating rear window by using suction cup clamps and also look at the repair of the TT Mk1's rear demister wiring. The suction cup clamps really help with bringing the glass to the fabric and saves you from having to think up of elaborate setups. My example of glass peeling is quite severe but hopefully you catch yours in time so it doesn't get to this stage.
Make sure you have:
- suction clamps
- orange good cleaner
- a sponge
- blue tape
- 3m single step primer
- 3m window weld or something similar like sikaflex 227
- soldering iron
- scalpal or sharp blade
I try and go into as much detail as possible so you'll feel confident when/if (hopefully you don't need to) you need to repair your rear window glass from peeling. I also test it out toward the end to show you that the repair is solid... or not 😜
The repair doesn't take that long and if you get it right the first go you'll be back up and running overnight.

Thank you. I watched a couple others and by far yours is the best!!
Ahhh awesome! Hope you can get yours fixed up. Mine is still holding up 👌
Excellent video, thanks for making the process look straightforward, nicely explained and executed. Mine has only just started to come away and will be attempting this shortly!
Thanks Peter!
It's the best time to rectify it. Mine was a bit too far gone but not the worst. Good luck!
Really good vid, thank you. I was a bit downhearted but having watched this I feel confident I can manage this repair myself. 👍👍👍👍
Hi Tony. Good luck on your repair and glad I could help!
Omg I prayed for such a detailed video for an audi. This is perfect and your such a handsome instructor with perfect skin. Lol. Ty. Im excited to start. Stay blessed 🙏
Best of luck Glamel and thanks for the nice words!
Really well done. Thank you for sharing. I have a 2011 S5 cabriolet with a few areas on the rear window that have delaminated. I’m going to follow your process so that it doesn’t extend itself all the way around! Thank you for sharing your repair video.
Thanks for watching and glad it's helpful. I have also used this same process for the Mk2 TT where the soft top has two "skins". I think it would be the same with your S5 Cabriolet... Audi made them nicer by making an inner skin to cover the frame. The process worked 👌
You made a great video. Do much details you explained. I saved myself so much money saving mine.
That's excellent! Great to hear Ed and happy driving.
Great video. My Mini Cooper Roadster just dropped the rear window out this past week. I'll be using your video as my template for the fix this weekend. You seem to have the most complete that I've seen. The only thing I'm going to do is completely remove the window to start. It's still held a bit, but I only want to do this once so I will seal the entire window.
As I stated below in my comment to one of the other people the primer is getting difficult to locate but I was able to call the local automotive paint store who actually had it on hand.
Thanks Thom glad you found my video helpful and super thanks for the tipoff on where to get the primer from. Seems like a rare item for some reason!
Good luck with your repair... I'd be too scared to remove it completely and start afresh!!! 🙈
EXCELLENT and well explained, amazing job looks awesome nice to see my wood effort included 😂
I just wanted pressure and improvised with what I had it worked well.
I used Sika SikaTitan 258 Primerless Windscreen Adhesive which is used in most car window screens these days.
I will be sure to point people to your video as so many have same issue.
Again well done Ian 👏
Thanks Brendan - and yes i had to feature all the wood ;)
Fantastic explanation and video! I'm about to tackle this job on a 2002 Cabrio with the same issue. A new top is pretty over $1000, so really hoping this repair holds!
Hey there. Yeah should hold! Mine is still all good and watertight 😉
Very helpful, thanks
So helpful!Thank you!
Glad this helped you! ☺️
Thank you Ian. Parts are $150 and labor, well . . . Most important, your video took the fear out of doing it myself. The bottom corners were separated, so now was the time to do it before it got worse. You're a confidence builder.
Hey - glad the video was helpful!! Good luck with the repair and hope it allows you to enjoy your roadster for many more years to come 🙌
Even without a top, I'd enjoy it. My first car was a '54 Austin Healey 100-4 in 1964.. I've wanted a roadster since. My '01baseball version lived in San Diego until I drove it, non stop to OH two years ago. Sometimes it's just fun to sit in it and enjoy the aesthetics.
The center sun visor and dowel to line up the spare tire on the rotor are just two of first class accoutrements I've discovered.
My next project is to install puddle lights on the bottom of the doors which will show the Audi logo. I've not seen any videos doing it with a Dremel to make the rectangle accurate. Thank you again Ian. @@ianpgonzaga
@@vicelse8980 I had to Google the 54 Austin Healy - looks like such a classic! Look forward to hearing about the puddle light mod in the Mk1 TT!
Hi Ian,thank you for your video really well explained!
I have a Porsche 996 with the same problem. Can I ask where you purchased the 3m products in Australia?
Good Job.
thanks for everything mate! very good info big help. i wanna try to fix my Audi .GOD bless
Awesome. Hope you good luck in your TT fixes!
thanks for the video Ian. the most detailed, informative, easiest to follow and well produced [time stamped, listed chapters etc] that i have viewed. are you in Australia? 3m tell me they don't stock windo-weld here and have no siliar product. $70-$90 if i ebay. i have only 15cm to repair and feel the rest of the tube will go off before being used.
thanks again for the amazing video. rodiebo
Thanks for the compliment! Yeah I'm in Australia. I can't find the same stuff but use the Sikaflex 227 from Bunnings and it seems to work alright too.
Awesome
Thanks Mr Bo 😊
I watched it a few times and still don't quite understand how the clamps actually work.
Obviously they do - but my stupid brain needs to think about it for a while.
This is way better than another car I've seen, where they have stitched a plastic window in it's place
Stiched it in! omg not only would that look funny but wouldn't it make it prone to leaks?
Awesome Video. Seriously!! Thank You. Can you tell me if you need to glue down that fabric strip that goes around the window on the inside of the glass?
Thanks John.
That strip is kind of difficult to glue down. If you can then do it but I tried my best and it's mostly peeled off. It doesn't impact the seal though. If you have it right at the glass that extra fabric strip is really just a vanity covr.
Could you possibly link the suction cups you used? I can’t seem to find them, all reviews on Amazon for similar types say they’re really bad
Hey, nice video! This is the best instruction I've found. I'm wondering, are you not going to glue the fabric inside the window?
Thanks! Yeah you can also do that strip too just to make sure it all stays watertight.
Thank you! Same method worked for mine, and I didn't find any leak from spray leak test. However the spot leaks after a rainy day. Maybe it is the water actually seeping through the fabric around the area? Do you have any idea on this?
@@555wonjoon hmmm. There shouldn't be any leaks if you've got it watertight. Maybe a spot was missed that needs a top up.
Very well made video, thank you very much. I have an Audi A3 carbrio that started peeling in a corner, only a little bit to leak inside. Can I apply the glue without the primer ? I don't know how to apply it since it is still very tigh, honestly I don't even know how to squeeze the glue, it is way tighter that the last leak repair in your video. Thank you very much
Hey there. I think the later models (like the TT Mk2 ) can be done but they're double skinned.
You might have to do the repair when there's some slack in the fabric.
Hi. Thanks for the video. My window has come completely out and no hood specialists will touch the mk1 TTs to rebons as apparently they just dont stick well compared to other models. Just wondering how well this has lasted for you?
Hi Emso my repair is still bonded and watertight since making this video :)
Hi Ian great video well explained! Can you tell me where to source the 3m products in Aus?
Thanks Chris. Not sure if they're able to be bought here any more... Might be able to get it in from online. Otherwise look at Sikaflex for something similar.
Thanks so much Ian
Hi, Great Video! Can you give a list of the exact products you used?
Hi hans.
- convertible suction cup repair kit
- razor blades
- citrus goo remover
- painters tape
- 3m window primer
- 3m window weld
- caulking gun
I think that's everything :).
@@ianpgonzaga thank you!!!
@@hansderksen1662 hopefully I didn't miss anything! It's all in the video though
Good luck!!!
Hi, what kind of silicone did you use ? I have to do the same on my Mustang unfortunately and i might put a vinyl or something less fragile than a glass
Hey there. You can see the product I've used using the timestamps in the description. Pretty sure I was organised enough back then so it's easy to find the info 😋
Hi buddy! Did you relax the roof? Or leave the tension? Thanks mikey
Relax it a tad. It allows you to place the glass "up" better. Pretty sure you can see it's relaxed in the video :)
@@ianpgonzaga thanks buddy! Ours is a a3 convertible! Ill just release the tension but not open it! 👍🏻
@@mikeyoakes180 yep that's it! You'll see once you undo it a smidge you're able to place the glass in a good position :).
Has your glass started to peel? Fix it NOW! Otherwise you risk it getting quite bad like mine (which you don't want). Does anyone have any tips to prevent this glass peeling from happening?
Sorry, preventing is not possible. It’s a glue aging process that causes the issue. Having a garaged TT helped but at 15 years I replaced the top. Thanks
Thanks @@Rhaman68
How much was the replacement ?
Can this be done the same way if the window popped out all the way?
Should be able to. Might need extra propping up from the interior since there'll be nothing else holding it until the glue cures.
How would i know all the old adhesive is actually adhesive and not left over canvas?
Good question. It kinda feels rough and gritty... Also you will see it's the old stuff too.
So good. Who are selling these sucker clamps?
Hey Francesco I just googled them and they show up in eBay and Amazon.
@@ianpgonzaga I've found a different type of clamps but they seem too weak.. (smaller) What's the name of yours? Thanks
@@Pikkey63 Gunson brand
@@ianpgonzaga found it! thank you so much!!
🙂
@@Pikkey63 woohoo! happy repairs :)
Can you please advise how I can get the single step primer Stan New Zealand
Hi Stan - might need to get it from overseas.
I have been trying with no luck any suggestion who to try thanks Stan
@@ianpgonzaga
Do you need to use single step primer on glass and canvas or just on Glass
I just used it on the glass.
@@ianpgonzagaThank you for your reply Stan New Zealand
@@stanstamatis3998 no probs Stan and hope you can get your roadster fixed up!
So I am having difficulty find the 3m single step primer, is the job still doable without it?
Hey Jeremy. Yeah you can still do it. Just clean the area up to remove as much dirt as possible.
I did this the other day without the primer on a Mk2 droptop and it still held.
@@ianpgonzaga thank you, and the video was awesome, it was very detailed, keep up the amazing work.
@@jeremyparton425 shall do sir. Thank you.
I'm not sure if you've found the primer but I just bought some this week. I ended up at a automotive paint store (NAPA Paints here in the US) where they had some of the little bottles like Ian used.
How to order product
I would recommend doing a search for the products. They may or may not be available in your country.

where are you located?
Hi Ann. Australia
@@ianpgonzaga bummer. lol hello!
@@summerdotcom 👋👋👋
What if it’s plastic
Should still work. The sealant stuff is pretty strong.
Please tell me this isn't a "professional" repair.
Hey Thomas 🙂 No way a pro job 🙈
I'm just a regular car guy who likes to get his hands dirty.
