The eastwood paint works great on plastics, dont thinks its a specific plastic/vinyl paint like SEM for interiors is, but it goes on great and is very durable. prep is key to a good looking and lasting paint job.
for prepping most parts and the grilles i just clean them real good first with dish soap & warm water, then a final wipe with rubbing alcohol. lightly sand/scuff everything to get a smooth uniform finish, i use scotch brite pads to scuff a smooth surface or 400-600 grit sand paper to feather edge rough areas, then spray 1-2 coats of primer & smooth if needed, then paint in 2-3 light to medium wet coats with some time in between each coat, but follow the cans instructions if they differ much for the coats.
