Ok guys I think I goofed.
I sanded down my Chevelle’s trunk lid and then used Fast Etch. I kept the metal wet for 30 minutes then wiped of what remained with clean rag. I waited about 30 minutes and painted with urethane primer. I did not use Pre Painting Prep.
That was Sunday, as of now the trunk lid looks good and seems I have good paint adhesion.
Should I sand the paint off and start over or is not using the Pre Painting Prep not a big deal?
Thanks again for helping me clean up my mistake lol!
