I would like to know proper technique and tools for preping painting abs plastic (motorcycle fairings) or a link. thanks
scuff with a scuff pad, if it has gouges repair it with plastic filler. prime and paint. there are additives out there called flex additive add that to the paint. and primer. we use lesonol at our shop and i sprayed a piece of tin exhaust tape to test it. balled it up and straightened it tons of times, it wouldn't crack
well, the easiest and most effective way is to us a medium grit paper, sand all old paint and primer off, and sand the plastic to a rough finish. This allows the new primer and paint to form a better bond. once the sanding is complete, begin with a automotive quality primer, and use a fine grit sand paper after each coat so you have a smooth finish. Apply at least three coats of primer, sanding each one, then paint your desired color, and again, use automotive quality paint, such as PPG. with each coat, should be light enough that it doesn't run. Sand smooth between coats, using wetsanding, for an explanation of that, visit your local paint shop. they will also be able to give you tips on finishing and clear coat if you want that as well.
