BMW original paint - need advice!
Posted: Fri Aug 31, 2018 11:27 am
Hope somebody who has actually painted a car can give me some help here. No opinions, please, unless you know for sure what you are talking about!
I've bought a1985 E24 barn find (20+ years) with incredibly good bodywork (virtually no rust ). I have done a few necessary bits and pieces and am now in the position to give it a repaint. I'm 99% sure it has original factory paint. Now, I have never painted a BMW before, only British & American cars. I see no point in taking it back to bare metal, as most of the paint is fine. I'm hoping I can just rub down the existing Black paint and go straight over with cellulose. Obviously, any repaired panels will be properly primed first. However, I'm not sure what BMW used in the first instance? I have bought isolator, but that is beige coloured. If I use this and it gets scratched, the beige will show - on the other hand, if I can get away without using it, I will have a far greater depth of Black paint to hopefully be able to polish any damage out.
So that's my question. Can I get away with painting cellulose over the original paint without isolator, without the risk of a reaction? By the way, before you ask, I have no interest in risking my life using 2-pack and I don't have an oven for using water-based paint.
If all else fails, I'll have to paint an old panel and see what happens - but I'd rather avoid the hassle!
Thanks in anticipation.
