ShopTalk: Refinishing Help

[Ed Johnson]

Hey All;
    I need some help refinishing some heads and maybe some shafts! ( I
stupidly laid some shafts on the back of my wife's car as I was spining and
sorting them. While I went for a coffee refill, she decided to make a quick
trip to the store and 7 brand new System Fit iron shafts scattered the black
top in front of my house.) They are pretty much scratched up but still
usable!
    Preparation, and putting the color on is not a problem as I have spray
equipment etc. and the knowledge of how to use it. The question I have is
regarding the urethane protective coating. The only time I tried to apply
any "clear" urethane to a club head, it came out foggy and wasn't "Clear" at
all! Anybody got some tips on how to do this stuff?
