If you over lap the peel ply and the lines are in different directions its a real pain to get out. You can pull and it will tear out in one direction but as soon as you hit a overlap thats in a different direction it will stop dead and you will have to fight with it.

The trouble with peel ply is that it does tend to turn to cardboard and can be very difficult to remove. Especially from deep moulds and parts with lots of shape. Bridging will also trap the peel ply in with resin etc. It can be a massive pain. I prefer to use perforated release fabric on its own, and only use peel ply in locations where I need to do any secondary bonding. Newbie, here! Does the perforated release film leave a nice smooth finish or do you see tiny bumps where the resin has moved to the perforations? Thanks,

My mould is quite deep, so I overlapped two pieces of peel ply onto the wet fabric (which is also in two pieces). But when I tried to remove the peel ply it had somehow stuck into the fabric and wouldn't come off. Is it better to just use one single piece of peel ply and accept that it'll wrinkle? Rick N
