Kb, I can do six med sized cranks after letting a mixed batch sit for 10 min. I don't thin my clear coats.
I wait at least 12hrs before doing the 2nd clear coat. Mix the clear coat in a medicine cup, you can get them at a drug store. Mix that batch really good, let sit 10 min then brush on the bait. Flex coat will take at least 24 hrs to fully cure.
