Just tried my first flat sheet 195g 2x2 c/f, and failed. I am using a polished aluminium table 2.4  x 1.7 Metres, No 8 wax, No 2 resin. I want a single thickness for decoration only. I waxed the Ali sheet and then tried to coat with epoxy, it kept producing pinholes which quickly opened up to bare circles the size of a penny. I brushed it over several times and gradually reduced the number of void circles but clouded the resin here and there, I assume with wax. I did press on and finish the sheet with Vac but had a persistent very slow leak, I just re pumped every 20 mins for 3 hours. The finished sheet (1/2mm thick) also shows tiny voids where the weave crosses. Perhaps I made some schoolboy errors here but a few hints would be much valued. I am wondering if everything was too cold at 12 deg?
