Thanks Stuart. That is pretty much what I was thinking. In my case it is going to be a few weeks until I can get to the clear. The airplane in question is a 40% Extra so the clear is really there for gloss and durability. I will be finishing up on the base orange today and then will apply a lacquer clear with gold pearl added. Then I have to wait for some vinyl graphics that will go on before the clear. I plan to block with 800 grit to get a good adhesion between the base and urethane clear. My worry was if the urethane was sprayed too quickly I would end up with something that would never fully dry like I had in the past.
