So my dad bought a different style new spoiler for his 2019 Mustang. It was "Primed, paint ready". I am struggling to get this spoiler painted and cannot figure out what is happening. Just tired of throwing money away and need members advice and help. My experience painting is very little, especially plastic.
We cleaned the spoiler with WG remover and let air dry for 45min. The shop I was painting in was around 90°. I sprayed SPI black base (qt of base is about 8mths old) over the black primed spoiler and the paint reacted only on the top. Looked like a dry desert ground. The other four pieces to the spoiler painted good with same base paint. So I sat it out in the sun for a while, then removed base coat wet sanding with 600grit. Once that was done I cleaned again and tried to add a SPI epoxy seal coat. It pinholed in the same spots. Let it sit over night and came back next day, wet sanded with 320 to remove pinholes. Cleaned with new bottle of 70% rubbing alcohol this time, let dry for 45min, re-sealed and it pinholed in same locations, only on the top.
Things in common:
Very hot in shop
SPI slow reducer is 1yr old, used in base spray and 2 seal coat sprays
SPI WG remover is 1yr old, darkened in color
Please help and thanks in advance.
