Help! Black lacquer looks like rhino lining

I sprayed a motorsickle tank with Evercoat G2 and sanded it slick last night. I let it sit overnight and then sprayed it with three coats of black lacquer. I put it in the sun about two hours after spraying and it sat in the sun about four hours. Now it looks like Rhino Lining. What the heck caused it? I'll sand it back to the primer this evening and start again from there.
Thanks in advance.

Letting it bake in the sun was the cause. You never put anything freshly painted in the direct sun. You have to strip the tank back to bare metal and start over, it can't be salvaged now. When you do it over, just let it sit in the shop, not in the sun.

Thanks, This is my first and last time to spray lacquer. I guess it is a little more sensitive than the catalyzed stuff. I've always sprayed urethane and never had this problem. After about an hour or two, I put it in the sun with no problems. Been doing this the last fifteen years. What a pain in the butt.

Sunset is right, that was your problem.
Lacquer paint dries from the outside in. When you put your piece outside in the sun it caused the wet paint underneath to boil giving you your unique finish.

Took it to bare metal, hit it with epoxy primer and then Dupont 99K and 7900 clear. Much better results. Now it has a finish I'm proud of and will be resistant to fuel. The lacquer is now relegated to painting my wife's picture frames and whatever else.
Thanks everybody.

"Back in the day" I remember shooting a hood in black lacquer. I moved the car out back and after a few minutes I looked out and it was covered with bugs. I stood next to the car and watched bugs flying over the hood and then all of a sudden looking like they had been hit by waist gunner and going down in flames. I guess they were being overwhelmed by the vapors of the lacquer thinner flashing off! The paint was dry to the touch, so the bugs didn't hurt my work. But man that was funny, those suckers were being knocked out of the air three feet over the hood!


Remember too that black is going to absorb even more heat than other colors.

Brian

like everything else it does have qualities that make it perfect for certain applications,but I'm no laquer expert,I only painted one show car with it...but it was the best one looking paint work I've ever done,that is until his wife washed it for him...I still dont know how she screwed it up so bad but it looked like she used sandy water and a pot scrubber. ..nobody can be that dumb ...I think she did it on purpose and just acted dumb. ..fine looking woman though ,and had the biggest rock I've ever seen on a womans finger..LOL everybodies good at something lol

What was really crazy was the surface was smooth but it looked like Rhino Lining. Really kinda neat effect but it wasn't his desired rat bike look. Neither is the shiny on it now.

I thought about it but didn't have any. He is content with a rattle can finish with flat black paint. He'll just have to spray this with some flat rattle can clear and he can have a rat bike finish.
I just don't want him to have the paint I spray lifting.

Mouse tracks? Holy cow. I guess you can't just remove them with a nib file.
