I don't think you will have any problem at all with the thicker wing skins. The wing will be stiff and stronger and may even fly better. The little bit of extra weight wont hurt, it will just make your plane a little faster. Most slopers end up flying with extra ballast anyway. The extra airfoil thickness is pretty negligible too. I doubt you would see a difference in airfoil performance.
I like to use Dave Brown's Southern Sourgum for sheeting foam cores. It makes a very strong bond that will never delaminate. I have also used wing sheeting tape quite a few times. Its kinda like double sided tape, except there is no film, just the glue. I've never had a delam with sheeting tape either. I did try 3m77 once. (Old type.) I noticed the sheeting lifting off the cores a little around the edges after I took the wing out from under the weights I used to press on the sheeting. When using weights, and not vacuum, there tends to be less pressure out at the edge of the wing. Using vacuum, that probably wont happen. In my case I put a little carpenters glue under the edges and the wing was fine. I flew that wing for years without a problem. Weldwood contact cement works well too. It's a lot like the Sourgum. Brush it onto the core and the sheeting and let it dry, then attach the wing sheeting. Very aggressive bond.

I'm building a Zipper that I purchased from one of our fine members. It calls for 1/64 ply skin, I have some 1/32 ply. I'm thinking that the thicker skin will make it more Martin proof... Will the extra weight and thicker foil make it too much of a hog? Also, will 3M 77 (old version) be strong enough for the skins if I use a vac/bag? Martin Cleary Cleary Bros.
