Ok Gary,
I've clear top coated 9 stunt planes with Dupont Nason 2 part auto clear.
-Dupont Nason Select Clear #496-00
-Activator 483-78
-Or 483-79 High Temp.
Do not spray this stuff in your home. At the least do it in your garage!
Have good ventalation, cover your skin, use a good paint mask/filter Minimum.
I spray a light coat, mix up more maybe 5 minutes later (6 or so oz) then the 2nd coat I put it on wet. Should have a big time shine after the 2nd coat.
The reason for the light first coat is 2 heavy coats will want to run.
Spray the bottem of the plane first, then the top so that any over spray is on the bottem.
I make painting fixtures to hold the flaps. elevators, rudder etc.
I tried using thinners etc to make a finish that did not need sanding & rubbing out. Non worked well.
I use it straight. I start wet sanding it out the following day. 1000 then 1500 then rub it out.
The cleaner your spray area & plane the better.
Bugs are your enemy. Q-tips & a steady hand are the best bug fix I have found.
Wait about 2 weeks if you can then put a coat of wax on on.
