Ive been glassing a few PU blanks with epoxy lately and notice that it seems to trap air under the cloth while laminating. little bubbles 1/8" or so. They can be squeeged out for th most part but it takes a lot of effort. Which is so unline when i glass eps. wet out let the epoxy soak in, squeegee off excess and done....no problems there. Anybody else have this issue? could it be the cloth im using(hexcel)? i would more likely think that it has something to do with the density of the PU foam compared to EPS but im not sure. Just curious if anyone else notices this difference when glassing epoxy on a PU blank.
