- The best release agents you find in shops selling glassfibres
- and resins. Also, a local boatmaker might help.
-
- There are waxes made especially for mold release purposes. You
- add 2 - 5 layers of these, letting each layer dry well and
- polish it before next. Shimonez (sp?) car wax works quite well
- too, but avoid car wax with silicone, if you intend to paint
- your fuselage.
-
- There are also teflon release films, that you apply quite the
- same way than wax, but they should be better. Frekote is the
- brand I'm using.
-
- And finally, for very difficult molds, you might try
- teflon-tape. It looks much like usual packing tape, is _very_
- expensive, but works well. I had a mold for wakefield pylon,
- one piece (mold, that is), with vertical sides. Couldn't get
- any piece out of it with wax. I then covered it with
- teflon-tape, and then I could almost shake the pylons out of
- the mold :-)
