Tricks to deal with debris in clear coat

Had a very bad experience this winter with clearing over white. Everything went great right up to spraying the clear coat. Any little fiber or black dust nib stood out with the white, never had this dramatic a problem with any other colors before. I did many of the common efforts to eliminate the issue (static gun, grounding, filters, paint suit, etc.) I tried picking out the debris with limited success. That car is done and another one is in the works and it's ...white! I'm hoping with the higher humidity during the summer months it might help. I was tempted to go single stage thinking that might hide the debris - but it might still show up when sanded so I kept with the BC/CC. If it's in the last coat they usually sand out but the first and second coat are killers. I'm sure there will be some debris this time around as it's inevitable so are there any other tricks to deal with debris in the clear? I've heard of using tape and there is a vacuum that made for debris removal. Anyone used one or have any other suggestions?
 
SATA made a mini vacuum for dealing with runs, it would probably cause more problems then it would help on dirt though. I don't see it listed anymore, but a product called a "dirt pick" worked well, it was a very fine wire with hooks on it to grab dirt while the clear was wet.

This is why I hate spraying white, or any light colors. I don’t even try to remove anything unless it’s completely dry, then dig it out with a razor blade n dab clear over it. I thought having a booth would cut down on this problem, but discovered that much of the contamination was coming from me and the air hose. If you don’t already, wear a suit and wipe off the the air hose. I had dried paint flaking off booth hose give me issues once.
 
Thanks for the tips, at least I know I'm not the only one. I'll pickup the picks and vacuum. Either may not work in every instance but it's good to have a few tools in the toolbox.
 
Some things to do:

New paint suit. Also wear a fresh spray sock on your head. Blow out and clean your area. Tack everything prior to sealer including the masking. Tack again after sealer. Everything. If this is BC/CC continue to do that after every coat of base (after flash just before next coat), including the masking.

Blow yourself off outside the paint area every time you enter the paint area. Use a tack rag in one hand to keep the hose clean. Manage the hose and hold it in your non spraying hand as you spray. Backmask and seal off the vehicle openings like 1/4 panel openings, cowl, etc. Don't just place a wheel cover over the wheel. Seal off the opening. Sealing off all openings by backmasking and backtaping is very important.
 
stuff happens. paint a black car, white bug will land....paint a white car...black bug will land....

hang panels verticle if possible...big big difference in results when doing that.
