The dust between the layers is a tricky one with white, because as you say a black dot does look pretty obvious.I have had this problem once before but lucky for me the area was hidden by a decal.The obvious solution would be to wait for the 2K to dry and remove the offending dot by very fine sanding, then start the clear process again.Sometimes though I have had success lifting the dot out with a very fine needle point and applying more clear to level it back out, but this can be troublesome and not without risk.The beauty of 2k though for me is that it often hardens and the imperfections seem to rise to the top so they are easier to sand away in the polishing stages.As long as the dot is NOT in the colour layer and you have enough clear on, you know you can safely polish it out later.Sure the clear will be a bit thinner in that spot but no one will know, only you.
As for the Mr Dry Booth, this is what I use as well and I've never had it crack or craze.I usually pre heat the booth for between 10-20 mins and after the last coat is on I place the parts inside and bake them for about 40-50 mins.Bearing in mind the dry booth only runs at about 40-45 degrees I give them longer than the 30 mins recommended by the manufacturer of the 2K because this is at 60 degrees temp.Air drying with no dry booth is usually between 12-24 hrs depending on the outside temperature.
I normally polish after 24 hrs.It's amazing how the dry booth's heat speeds up the drying times.
