Can you spray paint on to another colour paint, i ask as if i bought side skirts in red and cleaned them up and keyed them would new paint stick to it or would you have to take the old paint off
Thanks neil

If you want a good job then wet and dry all the way im afraid!

it shouldn't be a problem, just ensure that the existing paint doesn't react with the new, if in doubt use a sealer followed by a primer then top coat, a 2K base coat and lacquer finish should also be flexible enough to cope with use on plastic.

Of course you can, in fact i am doing this tomorrow with a set of arches from my MG, they are currently painted Xpower Grey, keyed them down with a scotchbrite pad, and i will be painting over them with RAL 5002 (iirc) tomorrow @ work

I wont be using primer either, no need in my case.

hi, im a painter, all you have to do is key them up, if theres any chips just rub them out with 400 dry, then prime them, dust it to start as a wet coat will cause reactions, then when dry go over with 400 again but dont break through, just enough to flat out any dirt or dust, then paint them, again to start use a half coat, are u using 2k or aerosoles? if its aerosoles theres not much build, dont b tempted to wack a load on at once, just aim for a nice closed coat meaning with no holes as u look at it, and scotchbrite will b perfect if u can get it if not like i said, 400, 500, dry or 800 wet up to u the finer the better realy but no more than 800

hi, i wouldnt say ud need an elasticiser as side skirts arent flexible, normal 2k is amazing and can take not only a lot of flex but can go to high temps 2, i painted my block in it and its fine 2 years later,

Here is a few pics from the bumper i painted a few weeks back, originally a metalic black.



Only minor repair needed to fill some drilled holes in the side, so very little primer added around the filled hole, then just lash the pain over in my custom carwash styled paintbooth after work



Few more coats.



Put on the car the following morning, perfect match.

i also am a painter and work in a bodyshop and you have had some good advice,i would say that you need to flat with 800 wet/dry with water to get a good and smooth key,using 400 directly befor paint and you would see its scratches so stick to 800,ive only done the odd spray can work with satin matt black on trim pieces but would say around 6 inches from your panel when painting.hth
