Hi again, Kirk,
I used 3M77 as a base to stick packing tape initially for the covering. When I peeled the covering off last night, only about 25% of the tape was well adhered to the wing, and I did use an iron to furhter assist in it sticking to the EPP. Apparently the adhesive on the tape did not mix well with the 3M 77.

I did a test piece of EPP foam with Sig Koverall and 3m 77, and it worked great! After curing I went over it with an iron on high and the Koverall shrunk nice and tight, very smooth, AND it added lateral rigidity. If you don't know what Koverall is, it is a polyester based fabric that is used on giant scale models. Very tough, and similar to the Icarex (I hope that's spelled right).

Regards again,
Mike
