Advice on Mold Release Agents

[awake4air]

I have been building some medium sized fiberglass parts for about 2 years now and have been using Partall wax paste and PVA as my mold release agents. I'm not too happy with using PVA as it sometimes creates little pinholes if not sprayed correctly. Does anyone else have some suggestions on alternative products. Wax and PVA is the only thing I am familiar with at this point. Someone told me once about a 3-part system, but I have yet to find it. What release agents do you use?

If the mould is now well broken in and has a good finish you should be fine with just wax and no pva.
Otherwise other options are permenant release systems like Frekote or Zyvax. These have two or three parts in the system and are expensive in comparison but release is excellent.
