I'm preping my a4 to get painted soon and want to blend lower plastics into fenders and bumpers . I have been taking paint down to metal repairing with fiber glass than bondo and primer . The big question will it hold up after painted. Please post any tips that will help my bodt stay in one piece.

 

I would'nt use fiberglass since it will crack leaving you with a ruined paint job. I think that there is a epoxy or plastic that is used instead. Any paint shop could tell you what you should use inplace of fiberglass and bondo.

 

Urethane, is what its called I believe. Same material as the bumpers but in a body filler form.

You will also need the same kind of paint that is used on bumper covers, it allows some flex instead of cracking/chipping

 

Thanks for tips I'll look for the epoxy and urethane . I went by a auto body supply shop I wanted to stop in at least I have an idea what I'm looking for now. I'm preping the body know might go with M3 fenders small rear trunk lip new front lower already have side skirts and I would like to blend those into the fenders. I removed all of the door molding and I think I'm going to fill the groves in the trunk to match the look I'm going for.My 00 A4 is silver with black leather a color combo I've always loved but, A color that I have always wanted to go with was on the 99 , 00 ? TT's it was a pasty lite grey (Flat look with a clear coat) if that makes sense. I had thought they called it a gun metal grey but from the gun metal grey's I've seen it doesn't seem to match whats out there. If you know what I'm talking about please enlighten me. I also have seen some of the newer dodge work vans with a similar grey .I am going to paint the car with a buddy of mine and am going to also have to find the paint to go with. I like playing around as much as I don't once I get into a prodject but I want to learn what body work material will stay together so I can come up with some wilder ideas in the future.

 

Yeah, there is supposed to be some kind of flex additive or flex paint that will allow some bending without cracking - make sure they use something like that or your body panels will crack under the paint, and split the paint job.

 

you need to find out what type of plastic it is. fiberglass will hold for a while, but wont last. but when you find out what type it is call a local paint suppily distributor and ask him what would be the best. there are just so many different types of plastic that no tellin what you should use

 

Thanks for your help I did bottom out side skirts a couple times pulling out of Dunkin Donuts HUGE entrances. I had fixed those with Bondo Brand Fiber glass Best stuff they had the autoparts store and skirts cracked again.I'm going to go with a urathane kit and going to the pro body shop store from know on.Its not worth putting all that effort in sanding mainly just to repair and paint twice.It will be a little while before I get the car to gether and ready to paint still looking at body kit, suspension setup, and rims to fit nicely .

 

I allready fixed them with the fiberglass before I asked for your advice - Just thought I'd clarify that thx again!

every Paint has flex additive already mixed in now a days... and dont mold anything together it will look dumb and it something breaks its a bear to get it off. example my friend molded a body kit on his zx2 and broke a front headlamp and needed to break the bumper away to get to the lamps...

 

While you're at it, blend in some nice subte fender flares. That would be awesome
