Video: [blue bumper with 80 grit sandpaper scratches and angle grinder scratches]
Voice: So here's the basics of sanding and filling scratches in plastic bumpers. First, we've got to clean the bumper. I like to use glass cleaner first...[robert cleans with glass cleaner], then I wipe with a towel wettened with wax and grease remover and follow up with a dry towel [robert wipes wet..then dry].
Now we've got scuff everywhere paint might possibly land to ensure it's going to stick and create a durable repair. As a general rule, you should scuff 2 feet in every direction from the damage [robert scuffs 2 feet in every direction.
First, try to sand them out completely with your D/A sander and 80 grit sandpaper.

Voice: I can feel that the lighter scratches are out completely, but the deeper scratches remain because I can pick at them with my fingernail. So I'm going to have to fill these low spots with filler.
Video [robert mixing filler]
Voice: Lay out a dab of filler and an even smaller dab of hardener. You want to mix about 10 parts filler to 1 part hardener. Mix it up with your bondo spreader until it's all one color--in this case pink because of our red filler.

And we'll just spread it lightly over these deep cuts and give it about 10 minutes to harden.
Video [robert sanding the filler]
Wrap 220 grit sandpaper around a foam block and sand out the filler. You might have to pause and clean up your sandpaper with compressed air ocassionally.

A trick to help cure the bondo before sanding is to wipe it with lacquer thinner. It will remove oils that come to the top and usually plug the sand paper. This can be done with fiberglass resin as well. Never use cardboard for mixing on. Use glass or get a metal tray or something that does not release particles of itself into the bondo when mixing.
what's the name of body filler are you using for that bumper ?
What kind of Bondo do I use? I'm going to work on the read bumper on my IS300 Saturday. So many bonds to choose from.
what kind of sponge do u use when u scrup the bumper?
is that a saab 9-3 bumper? lol I neeedddd that
appreciate the video!!
is the color code on that bumper b96p?
That's a lot of work..... I cover my motorcycle... preventing anything from scratching it.
Is that normal body filler?
my bumper has an tear in it how do I repair it
Erin Averyt plastic weld using a soldering iron and a small amount of the plastic from the bumper that is from the back side where it can never be seen
hey, I was working on my bumper and on one area I went through the factory primer and got to the actual fiberglass. is that still repairable or is it trashed?
evlution Just apply primer over the fiberglass. Wait 30 min. Wetsand 600. Apply base. Aply clear.
Uurg, wich filler is it 😢 thats the question for searching
Probably wont get an answer as i see all the comments. Will search further
It's after hours at that bodyshop and Steven who works in accounts receivable has gone into the shop to play bodyman. Look at his hands! Those are office guy hands not shop hands.
Is that filler only for plastic?
George GG plastic and metal
Well, this guy never bothered to respond to any of these comments.
I dont think is good to mix the filler on card board
Definitely not good.
VIP STYLE you not supposed to mix the filler on cardboard very unprofessional
Bondo??? And the way you're spreading it, it looks like you just got back and threw it on! How about spreading it to actually conform to the shape of the bumper in the first place?
Never use bondo on plastic bumpers or 80 grit sand paper folks!!🤣🤣💯....use a plastic bumper adhesive or a bumper patch kit!!....that bumper will be back in 2 weeks after the sun hits it!..and it all shrinks and cracks off!!💯
No card board for mixing filler!
Adhesion promoter. Start sanding higher than 80, maybe 150. Press firmly with the filler to fill in the scratches, lightly applying it doesn't work.
Plastic doesn't scuff like metal...no need to use 80 grit ...120 is rough enough
I stopped watching after the 80 grit sandpaper started 😂😊
don't be surprised many smash repairs use it but if you ask them they deny it.
The instructions on many plastic fillers call for 80 grit first
As soon as he pulled out the dewalt corded DA I stopped watching 😂😂😂
@@buttsnorkeler7107 Lol, yep!
I used 400
80?!?!?! Holy shit!!!! More like 320
lol ya right 320 ? that's insane, you be doing that for a while.
plastic parts shall not be less than 180 rough emery paper to polish you
No theres something called pairing looks like little hair from to rough sand paper
Never use body filler on plastic bumper use easy sand its a 2 part product thats meant for plastic repair and you didnt use adhesion promoter before applying the filler

Regular Bondo works fine...I've done it many times ...saves $$$ ..sands and feathers out great ...adheres awesome
never use ANY kind of filler on cardboard the filbers from the cardboard will be mixed and trapt in the filler causing it to crack
Never use regular filler in plastic bumper..It will brake.
hoo my God… this guy doesn't have a clue of professional bumper fixing..!
Too many no nos
As soon as i seen bondo on plastic i left this video as sson as i clicked on it. 🙄
Don't do this to your bumper!!! He destroyed the bumper lol
When he said 80 grit I was like🤦
@@shinew1142 what’re you supposed to use? Asking because I honestly don’t know and am doing a similar repair soon.
Among other things, you REALLY don't want to sit on that raised "crease" portion like you do with that orbital sander, that will cut it into a severely unwanted shape. I always did those "raised wrinkles" with paper in hand, gingerly. Same goes for finishing the final paint there. Just finish up to them (not over them) with the buffer and final them in by hand, or you will thin or go thru the paint in a heartbeat. And PLEASE tell me that is NOT standard metal body filler...one good push and it will crack if it is of ANY thickness, practically...the thicker the worse.
A friend of mine had a beautiful Corvette once that he had painted (at a supposedly high end shop) and they rounded of every corner like that so badly it just made the car look terrible...he was pissed. I recommend watching this to see how NOT to do it, then go watch a professional to see HOW do it (3M has one that's OK, a good body shop guy's version will usually be better). When you've done tens to hundreds of these things, you tend to get really good at it, if you have any brains and you give a crap. If you don't you won't be there long.
看个视频都要翻墙挂VPN,能看懂听不懂，你们用的很多设备在中国大陆都买不到。
This is so unprofessional
what freaking plastic filler did you use... thumbs down until i hear back. I need to fill in sanding dips and wavy sanding patterns on plastic interior parts. Thanks
Absolutely clueless. You must use filler for plastics that is flexible. The first bit of temperature change and the filler is going to start falling off and lifting in chunks
Dont pay attention to this guys
that's right, your video was much more informative!
+bunkerbuster stop you noob. This is a profession not a joke. Learn it
This video is literally the worsr video ever
holy shit take it easy.
Material waste
