As some of you know Ive been trying to flame for truck. I got a new gun that I never used before and didnt have it set right and shot the clear on the driver door and fender. I was about to go on to the hood and looked back and saw my clear dripping all over. I knew there was nothing I could do so I adjusted the gun and went on. The rest of the truck turned out great! I thought I would go back and try and sand the runs out of the driver side and shoot my clear again. When I was sanding I broke through in a few spots. I thought no biggie Ill just touch it up with the airbrush. So today I masked everything off and started to touch it up. As I was touching it up the color started to crack in some spots! I got pissed and just sanded the door and fender down to start fresh. Why did it do this? /ubbthreads/images/graemlins/shrug.gif

Don't know for sure, but my experience has been that when I squirt BC over fresh CC, some sort of reaction takes place and the stuff does just what you described.

Several times I've had BC bubble and crack and eat through fresh CC. (Took me that many times to figure out what was happening!) /ubbthreads/images/graemlins/shrug.gif Now I won't squirt BC on CC that isn't at least 4-5 days old.

Many paint companys offer a hardener for base coat, and it greatly helps "repairability".

Hmm so does HOK offer this? So if you were to wait a week or so it helps?

Your clear wasn't hard enough yet, and when you sprayed the basecoat color over the sanded clear, it "cracked" it. I've seen it happen before. I believe it's the reducer in the basecoat (that you are now putting over the clear that has not hardened enough) that "eats" little cracks into the clear. Your clear needs a couple more days to dry, then it will work.

if that doesn't do it, spot prime the area, then spray your basecoat and re-clear the entire panel. Call me if you have Q's, I'm in NC

You'll have to OK the number thru Scott and make contacts off forum.

That's a common problem with breakthroughs,especially with uncatalized bases and airdrying the clear.If it's a solid color you can layer up the base in very thin coats until it covers but it's tricky not getting it too wet to wrinkle it.Other than that priming it is the best way to hold it down.

Ko-seal works well for spot repairs and keeps new paint from wrinkling. You can sand it in under and hour then paint away after that.
