Can i use coremat in a laminate press? I press skateboards with a layers of wood, grp and carbon. I usually press them to around 7 tonnes to get good lamination and shape. If i add coremat into the mix will it just squish down to nothing ? Im thinking of using 1.5mm but would i be better of to use 3mm and expect to squish it down to 1.5mm in the press?....
