Ah yes the bugs!!! The clear I used was kicking in 20 minutes, not fully hardened but setting up some. Not much time for bugs to get to deep into it. But they do get on it. One thing I do is the moment the clear is where I want it, rarely does this happen, I turn the plane over. You would be surprised how much this keeps the top clean of dust and bugs and general junk that is floating in the air.
