Sheeting foam cores
Hey wildblue check this site on use of probond. wwwedge540.com. I used probond the first and last time the same day for skinning. Its alot of work getting the leading and trailing edges tite to the core. Takes about 300 lbs on a 35% wing also,still the edges are difficult for me. I bought a vacuum bag outfit and this is very easy to use. At about 6ins.of vacuum the skins are tight all the way around the core. Did 4 wing half's for a 38% Ultimate, they all turned out perfect.
