How do I get debris out of metallic color coat?

    I continue my attempt at a Duplicolor ice blue metallic finish. I had some small spots of crud in the color coat, so I finely sanded to level them, and reshot the color. I fixed those spots, and it looks like I created created some new ones. a few new specks of crud and what appears to be a small hair wound up in the new coat. I had the body totally free from debris prior to shooting, so all this is airborne. I'm spraying in my garage, so I expect this will continue to occur. If I can't sand them out, is there some other way to tend to this? Or do I just keep piling on the paint, hoping to get lucky?

    You need to get some tack cloth from an automotive paint supply place. That will kill the static that makes stuff cling to your guitar.

    I've been using a tack cloth. It doesn't seem to be helping much. Stuff drifts onto the wet coat, and I'm sunk.

    What about once it is on the color coat? Is there anything I can do other than sand it off and do it again?

    Any other options for places to shoot the color?

    I usually do it in my basement. Seal the room from the rest of the house as best I can, open some windows, and wear a good respirator.

    So far I've found a whisker or piece of lint or something in every finish I've done. It just happens. Unless they are huge I don't sweat them. I like to say there is a piece of me in every guitar I finish. Sometimes it's just specks or strands of propellant from the can. Looks like little white hairs or lint. They dissolve as more clear is sprayed. In most every case. The random whisker or speck of dirt that seemed painfully obvious initially is hard to find by the time I'm wetsanding or assembling the guitar.

    +1,

    After you level and buff, at least they are shiny, and in most cases, no one will ever notice. You will know they are there because the whole process was a big ordeal for you, but others won't even notice.

    To be more specific about your question.

    Metalics suck. You have to spray them just right the first time, because you can't really sand and repair them. Almost always have to spray a fresh coat to get everything back even again.

    If you notice something land on your finish while spraying, STOP, let it dry, then try to scrap it out/off. Then hit it with another coat if you make a mess.

    +1 sometimes a good set of tweezers and a steady hand will save the day if you are able to stop in time.

    It may sound crazy, but I try to clean out the garage with a leaf blower the day before I do any spraying.

    Spray the floor down with water a half hour before you spray. Dont stand right over the body when spraying, just extend your arm straight out.

    All good suggestions. I'll roll with the clear (assuming I can pick the big hair out) and see how it turns out.

    After this, shooting a solid color will be cake...

    So I just put down my 4th coat of clear. I picked up one nasty speck of debris on the last pass, and didn't notice until I had already locked it in. It is on one of the faces, nowhere near an edge. Is it safe to start sanding out debris at this point?

    I'd wait a couple of days but as long as the paper doesnt gum up it should be ok.
