hey guys , i was at HD today buying more foam/stringers/glue and when pulling down the 4’x8’ sheets of 1ib eps i spotted what looked like urethane foam blanks in the back…
pulled em out and it said poly icate something??? …
they were sandwiched in between aluminum skins…is this foam suitable for a surfboard core?? maybe skins…seemed pretty low density…
anyone with experience with this type of foam???..-matt
