Good job! Just FYI, there are products in the Autobody industry specifically for paint adhesion on raw plastic parts. They work extremely well! A bit pricey, but well worth the cost. Sanding with a very fine grade scotchbrite pad is helpful, but adding an adhesion promoter to the plastic before the painting is tremendously recommended.There is not much worse than the loss of paint adhesion on plastic, to have to redo. By the way, I own a Autobody shop and have been painting since I was 13 years old.
I have a few undamaged shells that I have plans to do wild paint schemes on?
