Fiberglass release agent?

Many interesting suggestions. One that has worked for me is using a can
of "dry" lubricant. The type I used, can't remember the brand, goes on
leaving a tightly adhered powdery look. Several coatings were made after
the solvent flashed of each time. This stuff is designed for surfaces
that cannot tolerate oil that might attract dirt.

I have used this product to prevent sticking on both fiberglass lay-ups
and epoxy and silicone rubber castings.

Another product that I have used in a pinch is a product similar to
LPS3. It sprays on and leaves a thin waxy film (like paraffin) with no
contamination to the part. I think this stuff was originally intended to
protect guns in storage, leaving a dry non-smeary surface when the guns
were handled.

From looking at the internet, most release agents are wax based products.
Can I just use paste wax for the mold?

Any other suggestions?

Thanks

Carnauba (sp?) or most any paste wax that doesn't have silicones in
it.

Unless you got a lot of curvature, plastic 2" wide packing tape works great.
Or just enclose it in thin sheet plastic so that there are no creases.

I've always wondered if small plugs could be covered with heat shrink
plastic like used at Blockbusters on video tapes.

Would sure get the wrinkles out.

I would think 3 or 4 heavy coats buffed between each coat to a high gloss
would work OK.... 1 or 2 coats more coats between multiple parts...
