Default Inner fender paint problems

I have a 2000 FRC and I'm doing some painting and cleaning under the hood. I wanted to paint the inner fender wells but every time I try to the paint orange peels bad. I used simple green to clean, sanded, acetone to wash and orange peel appears. I sanded them down again and washed with mineral spirits and tried to prime, orange peel appears. Is there something else I can do to get it right?

What are you using to paint with? What type of product are you using and application method?

Sounds like you need adhesion promoter before primer. Makes a big difference on plastic.

Just trying to spruce them up with Semi- black Krylon spray paint. I also tried the Krylon Fusion paint for plastic and it did the same thing.

The issue may not be "orange peel" so to speak. It can be a contaminent that is on or now in the surface. I know that you wrote that you used mineral spirits...which I have never used....for prepping for painting automotive paints..."rattle-can or otherwise. Try using a wax and grease remover designed for paint. Apply it to the panel with a CLEAN paper towel...then with soome Clean paper towels...wipe it DRY.

When applying the paint. DO NOT try to get it wet. Try applying a mist and slowly build up your THIN layers...allowing them each to dry...and they should dry quickly due to being applied thin. Then when several thin coats (4-6) are applied...you then can apply a "wetter" coat to melt evereything in together. Just be casreful that you do not get it soaking wet...because the solvents in the "rattle-can" can penetrate down and start the whole process of what I feel is "fish-eyes".

Most "rattle-cans" have a built in "fish-eye" preventer....but...if the surface is badly contaminated...IT will still fish-eye and look like real bad orange-peel.

Your inner skirts should be a black SMC material. I usually condition them if they are looking poorly...instead of painting them due to oil and what-have-you getting on and in them over time.
