Topic tags/keywords: question

I made the mistake of spraying some boxes with lacquer too far into the heat of the day. The surface developed almost imperceptible alligator marks (crazing) that you need to magnify to see, but they do affect the quality of the surface in appearance and feel.

I was thinking of trying to amalgamate the surface by spraying lacquer thinner. Any tips, techniques or other advice anyone can give me?

If you are spraying nitrocellulose lacquer, the next coats should melt into the previous ones. If the crazing is minor, you might try sanding it and reshooting. If it’s hot where you are adding some retarder might help as well (not thinner). if you are using rattle cans, you’ll need to wait for better weather.

I’m glad you asked that Tung. Actually, one was done with big box nitrocellulose lacquer, and the other was done using pre-cat lacquer. They both have similar issues, but with a slightly different overall effect.

I’ll probably wind up sanding and re-coating, but as I try to learn, I wanted to try some different fixes first.

Thanks for the feedback.
