I spent Saturday painting my rear bumperettes Arctic Silver to match the body. Lot's of prep and sanding but the final look was worth it.
After cleaning with acetone they got a 2 coats of plastic prep spray
Then 3 coats of primer, sanding with 600 and 1000 wet sandpaper between coats.
Then 4 coats of arctic silver base coat sanding with 1500 grit between coats leaving the final coat un-sanded.
And finally 4 coats of clear coat, sanding between coats 2 and 3 with 1500 grit
All the material was purchased from Automotive Touchup and matched perfectly.
