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 planning on building a few fiberglass pieces from a mold this weekend
but don't have time to order a release agent.
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

Dave
