Having made about 8 medium sized carbon fibre parts now, I am less sure of release agent approach than when I started. I spent a year of part time plug making to build my most recent plug, coated it with 5 coats of easy-lease and on demoulding it destroyed the plug and severely damaged the mould. I have had one successful easy separation from a mould on the smallest of my parts and that was using meguiars wax x 10 coats.
Easy-lease just doesn't ever seem to work for me and when I've asked about problems with it I'm told it's got a shelf life (of what I don't know) and even in a sealed tin it goes off - bad news given the price it is and the lack of confidence that induces when using it!
What combinations/approaches can I use to get the best release when resin infusing using the uni-mould system and epoxy? Can I lay down some P120 sealer on the moul sand then add easy-lease on top or even PVA? If I look at Meguiars gold, PVA, P120 and easy-lease, what combinations give the best part release based on your experiences please? Grateful for any advice as this is a complex mould and I can't afford the time to go back to the start...
