I have tried priming with plastic melding primer (rattlecans) and just shooting straight rattlecan rustoleum 2x directly over laminate , but when masking , even masking tape that has had the adhesive weakened considerably will still peal the paint off the laminate.

The laminate is really slick and the only thing that seems to stick to it is spray 77 or laminate itself when heated . Not sure if the 77 would peel up is a precoat is sprayed first before painting or would affect the paint layer such as orange pealing etc.

My next foam project is going to be a remake of the 10' Woodys Pusher I did with DT foam board and Tape Brothers tape. Fuse was done in laminate with primer and Rustoleum 2x ...but had the bad peeling problem.
This time I may just use hot wire cut EP with the paper painting mask/white glue covering method and then laminate it.and follow with acrylic..but need to get the paint to stick really well. So whatever method I need to prime will be crucial to making the acrylate stick.

Fuse will be block frame of peeled DT foamboard with balsa corners and frame glued exterior on the frame, then laminated open frame style and painted with Acrylic.
Have you tried to roughen the surface up some first? Try using a red scotchbrite pad first to give it a bit of "tooth" for the paint to grab. Then clean real well before primer.

I'm not a fan of DTF, but I just got done with a FT Viggen made from it. After applying Blenderm tape to top and bottom of the hinges I used a light coat of oil based polyurethane wiped off with a paper towel to seal the paper, sealed the edges with hot glue, air brushed it with water based Apple Barrel paints and then sealed it with WBPU.

A lot of work and I'm still afraid of the paper coming off of the foam!

Your jet looks fantastic. I think you protected it quite a bit. The paper should stay on for a long while. In the meantime show us a video of your beautiful creation in the air!
I have had similar reservations about papered DTFB. I too used polycrylic and it has worked well. But you can't sand or shape DTFB with paper on like you can with Depron or MPF. I have been using MPF and really like to work with it. No paper to worry about. It's thicker and doesn't need the strength from the paper.

Thanks! Problem with adding all of the extra coatings is that it adds weight.

Here are a couple of Jupiter Duck planes. I just airbrushed Apple Barrel paint, used a Sharpie for the panel lines and rivets and then brushed on the WBPU. These are cool little planes!

I've got to recover 3 planes, 2 well all 3 are large, I have doculam for the covering, I think I'm going to paint the design on the inside, like I did the bingo, and pinstripe the out side now what colors.
