Watch the water-based glues though...they SHRINK while it dries and can WARP the carp out of your wing if you don't weigh it down.
forgot to mention this! i always do both sides of a wing panel at the same time so i dont end up with a banana, i also hang them to dry. don't use brown paper over the soft beaded foams as it can totally distort the profile of the wing, i use 2.2lb. foam that is a little stiffer than pink foam. for white beaded foam you can use newspaper but the wing might need spars added. on my wings i don't use any wood at all, even the leading edge is foam. i've been hooked on this method since i read about it in rcm back in the mid-'80s
if i ever get something better than my cheapo pc-cam i'll post a few pics of the process. anybody who wants cheap and quick should try this, for me it is easier than sign vinyl or glass and i get a perfect, wrinkle free finish every time-something that can't be said for packing tape or vinyl.
