BMW Z3 M Coupe Sill Rust
HTML-код
- Опубликовано: 15 апр 2020
- @RedishMotorsportbmw show how we tackle Chassis-bound Sill Rust building up on the BMW Z3 & M Coupe models. This is hidden rust behind the Outer Sill Panel.
This owner had just recently bought his M Coupe and after watching our other video on Front Sill Rust:
• BMW Z3M Coupe Undersid...
he saw he was also suffering with this common problem.
He made a booking with us to rectify the Front Sill Rust.
However, on removal of the Outer Sill Panel we discovered the Rear Sill section was actually suffering with rust worse than the Front Sill.
So a decision was taken to take care of the Rear Sill rust (and Central) whilst we had the Outer Sill Panel removed and had advantageous access.
You can see we use a mixture of @POR-15 products to neutralize any embedded rust, and then protect the bare metal.
Then it's on to High Build Primer, Sprayable Seam Sealer, and Top Coat Colourings.
Once all paints & sealers are cured overnight, we carry out the all-important Cavity Waxing and make a good point to show some interesting video angles from underneath.
If you have a BMW Z3, M Coupe, or M Roadster and are suffering from this very typical Chassis-bound Sill rust and would like to get it treated to an extremely high standard by a BMW specialist then please get in touch:

Great vid with clearly photographed and described information, thank you for sharing 👍
I love this channel and this type of videos. Really apriciate you take your time to film this and post it to youtube. Cheers from Croatia
I used their reinforcements, but the finish quality of Balkan's finest "professionals" cannot compare to Redish work ethic. I even gave them a laptop full of Redish videos to consult, helped none.
Thanks Ivan, it's really great to read such nice comments. We're so pleased you found it interesting. We love what we do, and we love creating videos and sharing our work with the world via our RUclips channel.
Thanks Idok, appreciate your info and kind words. Thanks for using our product too!
Nice work as always and Z3 Coupe, lovely!
Great work. Refreshing to see what you do & how you do it with great explanation of each step. Keep up the great work, you might see mine in the future. Atb.
Thanks Technique, looking forward to it!

i use por 15 on my evo ! glad you guys use it also :) !
Yeah it's good stuff Eddie
Attention to detail is unreal!
Thanks Ash, appreciate that!
I love the attention to detail. Could you recommend a good aerosol spray sprayable stone chip/seam sealer?
Great and thorough job I’m impressed only thing I would do is remove the plastic screw grommets as rust as you know likes to hide
Hi Anthony, thanks for the kind words. Yes, good recommendation. We'll do that next time. Thanks.

Prior to cavity wax, do you typically perform a visual inspection for any corrosion on the interior of the sills and if corrosion is found what methods have you found best to remove it before cavity wax application?
Great work! I’m about to repeat similar job on my Z3 and I have a question about those painted threaded bolt holes? Were you able to screw into the bolt holes easily after all? Any recommendations? This would be much appreciated .
I love a good Redish video, but they don't half make you worry and depressed about your 4 wheeled baby
You can’t use a car you care about in winter in the UK.
Hi James, what is the product you use for the spray on seam sealer? Is this something I can purchase from you in the BMW e-coat colour? Thanks and hear vid
What brand of cavity wax are ye using?
James have you never thought about opening a joining bodyshop? The respect your work ethic and level of detail must attract people who want body paint jobs with the famous Redish professional standards
Hi Chris, it's a great question and something I've considered many times over the years. Our Restoration Technician Dave was also a paint sprayer years ago so we even have a 'head start'. Just need to take the plunge and get a new building, plus an angel investor to get a high quality production setup! haha.
@@RedishMotorsportbmw I'm sure it would be successful, but i know what you mean about new ventures
Great video thanks. How much would a proffessional job like this cost?
What chemicals do you use to remove the undercoating BMW puts on from factory
I wish my E39 M5 sills looked this good. But great info on what products to use!
Hi Jaime, thanks for the reply. Glad the video was useful!
Have you tried hammerite rust remover gel , i was really surprised at the result for what is in effect a diy product
If you read scientific studies on rust converters you learn most are acid based which seeps into the microscopic pores of the metal and down the line causes new corrosion. It's a hard decision. However everyone always says once rust starts it will come back no matter what, so I guess all methods from that point on are just cyclical 10 year restorations.
How much does such of service cost roughly? I'm aware that it will be case-by-case dependant but just to get an idea?
Hi can you tell me how much would that cost to do a job like that and that is great video
What did you Remove/grind the rust with
Wax was cool
Thanks Cameron. Glad you liked it. Yeah we think it's a cool thing to video too!

Great.....something else to tack on to my long-term list of things to do
You can do it!
I've been doing some restoration work on a 325ti & your videos are inspiring me to keep at it. The standard of your work sets the bar very high!
Where do you get sprayable seam sealer? I have searched everywhere but I can't find a suitable product. What brand is it? Is it called "seam sealer"? Thanks
Did you check the Wurth catalog? I'd bet they use something from Wurth.
I believe the sprayable seam sealer is proprietary to Redish Motorsport.
roughly , as a guide , what would a job like that cost ?
Hi does anyone know the part number for these riv studs?
Hi Tony,
It's this sort of thing:

Compared to a M3 e46 this is magnificent in build quality
Very true Mani!
Absolutely fantastic quality of work, just surprised that you left the cavity bungs in and painted over them at the ends of the sills. Is there a reason for that? Not a moan, just an observation.
Thanks for the comment Julien, you're right - it wasn't until near the end I realised the same thing. I had a poke around the area with a pick and lifted the edge flaps of the grommet and was happy there was no hiding corrosion so deemed it acceptable. Good spot though.

Anyome in ireland this good hit me up i need work done
all this nice work and you put again old rusty bolts???
as he said, the customer is getting the outer sills redone at a body shop..👍
and didnt even wash the original mud off the sills ,,, thats attention to authenticity .
Two things I've realised in life. 1. Perfection is expensive. 2. Everything has it's time.
Good comment!
How much would all this cost?
Think I saw on another channel it was £1400
Sorry mein Englisch ist sehr schlecht, aber wichtiger ist wie sieht der Schweller von innen aus?
Why not reveal you and your garage.
Good questions Alimechs, we're about too actually. Obviously people know the name and can find us easily on Google, Facebook, RUclips, and Instagram etc, but we're recording some new content now during the Lockdown which including myself in front of the camera for a change.
I'm afraid to discover the full extent of the corrosion on my cars, I must bring them down to you 2 x E34s and 1 x E39
16:46 I thought it was spanish
You can’t use a car you care about in winter in the UK. There’s just too much salt on the roads.
Seal sections lol I presume he means sill sections..?
Typical UK car...
True
Ask your self, do I leave in an area where it snows? Then rust is inevitable an any car. Its a Z3, not a zed 3.
Z is pronounced Zed in Europe.
thats totally lost in typing ,,,
