If such a thing exists. I'm having a heck of a time keeping stuff out during the clear coat; not so much of a problem with ReRanch cans for the color. I wonder if it's because I use an HVLP sprayer for the clear and it kicks up stuff. Not sure how as I've sectioned off a part of my shed as a spray booth using plastic drop cloth that covers walls, floor and ceiling.

Should I be doing anything different? Do people wear bunny suits when they spray? Maybe immediately move the guitar out of the spray section and into the curing area? I know some folks here spray outside, seems like that would be more problematic, but willing to try it.

Also, if I just want to "screw it" and start completely over, what's the best way to strip using lacquer thinner without getting too aggressive (i.e., not remove white base coat or sand sealer)? Thin it? Use cloth vs paper towel?

Thanks!

You might be creating static electricity while shooting with them HVLP gun and the plastic. It will draw dust particles in the air into your spray pattern. I shoot in my down draft spray booth and outside without problems. Just scuff sand to get contaminants out, then shoot more clear

You guys would have a heart attack if you saw where I paint. Laughing

No, I don't do anything special, and never had a problem with dust and stuff.

Ha! Pics or it didn't happen Marksound Very Happy

Lon - I didn't even think of that, my draped space *is* pretty tight.

Ok, it was really nice this morning so I went out and shot clear on the lawn, it turned out much better than anticipated. I still got about 3 dust particles that I could see (I do not know how you guys get nothing...). I've read a couple different ways on how to handle this, do I wait 24 hours, then scuff sand out or is a 3 hour wait enough? If I wait 24 that really messes with my '3 of 3' routine. Sometimes the dust is so deep I get down to the color coat, which then gets me uneven color blotches (see my other thread). Ugh...what a pain.

Thanks everyone!

Spraying a light dusting of water in the air and waiting a minute for it to settle on the floor seems to help weigh some dust down/stop it getting kicked up
