Dust string on enamel paint

[gpal]

Hello, just painted my car model with Testors enamel paint and noticed a dust string in the paint. Can I sand out with 600 grit after a few days and re shoot that area?Any suggestions from you experts out there would be a big help. Thanks, George

Absolutely.   But I  would sand it with 4000 grit first since it's only dust.  If that won't get it, you can always go to progressively coarser grits.

Did you use a "tack rag" on your model before painting? This seems to help quite a bit in keeping dust spots out of your paint jobs. If you used enamel paint, I would wait a week or so before sanding and respraying. I've done the same thing with a lacquer paint job and it came out great without having to strip the paint and start all over.

Also,

You didn't mention whether the top coat is metallic or not.  If it's metallic, the sanded area will look different in the final paint job unless you respray the whole model.  If it's a non-metallic color, you may be able to just polish out the imperfection and not respray at all.

Some times the surface you're going to paint can become contaminated on your way to the spray booth. I'm not sure where your living or your weather conditions, but this can sometimes create a situation were the models body is effected by static electricity and this will attract any dust particles in the air. this can be caused by walking across a carpeted area or if there is low humidity and wind blowing outside even. I also learned from a 1:1 painter a long time ago to not wear and flannel shirts in the area were you're working on getting a surface reedy for painting. Any static electricity will pull in any lose fibers in the air. As pointed out by Steamboat start with a very fine sand paper. You can always go to a courser sand paper if need be but your better off going after this with a very fine sand paper and very light pressure when sanding.

All good advice above.

being that you have used enamel, best to give it time to gas off (dry) before attempting anything.

with enamel that can be some time depending on your environment. Temps and humidity.

Do you think 7 days , it has been inside on bench with low humidity room and warm temp?

Thanks, George

You can wipe it down with a used dryer sheet to remove any static electricity before painting. It also works great before using panel line accent.

Just make sure it's a used dryer sheet; fresh dryer sheets can leave a residue.

No experience with the latest formulation enamel in rattle cans these days.

The longer the better, weeks not days is what I've heard. I'm sure someone 

here more knowledgeable using enamel rattle can paint might chime in.

When done painting,if you use a coat hanger method, hang it up..Dust lands and doesn't go upward..I've been doing that for years..Hang on a line so the dust doesn't settle..
