Group: Forum Members Posts: 9, Visits: 51	Hi, Do you foresee problems if I use a sheet of polypropylene (smooth, no texture) as surface for wet-lay sheets approx 1.2 x 1m? I have been told glass is ideal for this (thank you Wozza!) but I want to create a shallow curve in the sheet. I can test on a smaller scale but I'm not sure what might happen on this larger scale regarding release, reactions and warping? Many thanks for your advice.
