This has come up recently and I'd love some input.

Occasionally I encounter a work of art that has been coated in clear two-part resin (usually a collage on wood panel then coated).

What is the best way to wrap resin-coated panels for transportation and storage?

I have been wrapping in 1/8" ethafoam sheeting against the resin, then wrapping the whole package in 4-mil poly-sheeting.
