I used dupli-color lacquer paint and clear lacquer spray cans . I had research through all the forums and everybody says dupli-color spray lacquer is fine. I know it isn't hvlp quality but it looked very nice after I hand buffed it. I really didn't even have to wet sand that much because it was glossy enough, I didn't want it gleaming because EVH didn't even clear coat his original frankenstrats.
I just have never read of any similar problems like this with others who have clear coated before. Only a couple of coats may have been sprayed with 65% humidity, nothing more than that. Its like the clear coat held fine, I would have never noticed a problem until I saw that tiny 1/8 " sized little ding in the finish. If I would have known I would be sanding the whole thing down again I might of just put some clear lacquer on that tiny spot and hoped it never would get banged around.
You could take your finger nail and scrape up sections of the clear coat like you were scraping a decal off a glass window.
