Now that I think of it, I only have one elevator covered, the rudder and other elevator are just prepped with Stix-it, so I could use Nitrate to fill the cloth first, if that will make it easier on me. BTW my detail gun is from HF, but has the plastic up with screw down lid, not a metal one with the press on lid, this is why it leaks so bad, very poor seal of the lid to cup. I wonder if I can just get a metal cup that will fit the gun.
