Default White Foam and Paper Wings? Poly?

I'm a newbie and covering white foam the (whole wing) wrapped with thin paper should I use polycrylic or polyurethane. Can I put the wings in the beds while this dries? I would like to be able to do that. Low temp film can/will go over this when done. Im making several for other people to build themselves.

If you are covering with film, why use the polyurethane or polycrylic? I don't see the need for it...

I have agree, If your planning on covering the wing with film all your really doing is adding time and extra weight to the build. The iron on film adds the extra strength needed for this.

Default Let me rephrase that

What I mean is what is better for applying the paper to the foam wing polycrylic or polyureathane. Will either one make white paper look like white film? Tips, Links and hints appreciated.

If you're covering the wing with paper, then use the water based polycrylic.
Regular poly urethane might attack the foam.

If you want a smoother finish, you can use some pre mixed Spackle to fill the bumps and dents.

You'll have to test the paper and polycrylic to see what color you end up with, white sometimes gets a little transparent.

While the WBPU is drying, I wouldn't recommend it coming in contact with anything you don't want stuck to the wing.

There are a few theads on how to do the finish.
