Good tip Mike.  I use a two foot board mostly and a sanding block along with a trouble light to look for lows and highs. I'll give the light misting of black paint a try.  I put the primmer on with a roller . I  have premarked  with a pencil any low spots I can feel with my hand. The prime I use I have mixed with micro so I lay it on thick in the low spots. Board sand it later. Your suggestion will make it all that much better.   Take care---------------  Chris
