This weekend I stripped and painted an original fender extension to replace the junk repro on my 70 Chevelle. I used the same Omni products, etch primer, primer surfacer, primer sealer, and base coat as I did to paint the whole car about a year and a half ago. The clear coat I used is what the paint store called a "house brand" clear coat made by Smart technologies. I did not have any issues with these products when painting the whole car but when I applied the clear on this fender extension today it fisheyed. I got the base coat put on last night and then this afternoon I sprayed the clear. I didnt think to clean it off with wax and grease cleaner today but I did gently wipe it down with a tac rag. The only thing I can think of that caused it may have been the exhaust from my salamander heater that I ran for about 10 minutes today.

More importantly, what steps do I need to take to fix this? Can I just sand off the clear, spray another coat of base and then re clear? Or do I have to sand everything off and start all over?

Thanks in advance for any advice!

Sand, CLEAN, then respray.

My initial thought was to clean with wax and grease remover, sand with 600 grit, clean again, apply another coat of base, clean again, and then re clear. Does that sound right?

I would do just that. dont sand without cleaning, youll just rub that nastyness in deeper.

I talked to my paint store today. He suggested to clean it, sand out the fisheyes while trying not to break into the base coat, clean it again and then reclear. He also said I could sand the clear off with 1000 grit, spray another coat of base and then reclear. I think I am going with option two.

Thanks for the replies.

Sand the clear with 600, to give the clear something to stick to, clean it and then reclear. No need to rebase it.

When you re-apply the clear, fog the first coat on to lock any possibly remaining silicone in place. After that you can apply full wet coats as desired.

Thanks for all the tips. Hopefully I will get time to re do it sometime this week.
