Your welcome Don, if I helped.
tcodi- I tack between coats sometimes- if someone comes into the booth while i'm shooting, and I double the flash times before the first coat of clear, mainly when I shoot a tri-stage. The clear penatrates so much that I've had the basecoat shift under the second coat of clear off of a repair spot. Once bitten- twice shy.....also depending on humidity, you can adjust your mix some on your clear to help it flow by decreasing your solids by up to 15% max.
Get yourself a Viscosity cup & learn how to use it (no- it doesn't go on under anything before you paint). Good Luck...
