I am using Polymax from FarmTec and started by trying the 3M transfer tape on the roof. It sticks great but the Polymax does not necessarily lie flat.
At times it lays good other times depending on temp it tends to bulge in between the tape strips. I don’t know what it will do in the sun.
I didn’t like the top so decided to use vinyl top adhesive on the sides. It worked great. Just like I laminated it.
I used sprayable with an old paint gun and the sides went on really fast. Individual aerosol cans would work but it would take a quite a few and be more time consuming.
That was last weekend and I have been busy since but have had time to fit the hatch and put on some of the trim. But!!!!!!!! Today I walked by it and noticed what has been a bodyman’s nightmare ever since the lead was removed from paint
transparency 
I can see every place I mudded in knot holes. I’m not sure how much this will show in the sunlight and most of the spots are near something that take your eye away from them. If not maybe some graphics. I’m not worried . this camper was to learn on and will eventually go to my daughter in Oklahoma. She is already talking about airbrushing a scene on it.
I used clear sealer but would recommend if anyone is glueing Polymax on tight to use a colored sealer or paint to obtain a uniform base underneath otherwise the dark spots will show through.
All in all I really like this stuff but have found things I will do different next time
