I have used the new formula to build some balsa sheeted foam (regular white foam) wings recently. Did some tests on pieces of scrap first. If it drips or puddles the stuff will eat right through the foam. When sprayed at the recommended distance and done carefully, there were no problems. The sprayed surface looked good and had no etching (I sprayed several light, quick coats). I made sure to let it dry long enough before assembly and my wings came out great. I definitely believe if it needs to be put on thick, put it in a container first.
