Tammy,

Perhaps you are confused.  Marvelseal is a barrier film product and not a
spray or coating.

Here is a product description from a vendor:

"Marvelseal 360 is an aluminised polyethylene and nylon barrier film.
Marvelseal 470 is an aluminised polyethylene and polypropylene barrier film.

Both will resist the transmission of water vapour and other atmospheric
gases. Material is flexible, economical, easy to fabricate and is used for passive
humidity controlled shipping or storage bags. Is ideal for lining the inside
of shipping crates and exhibit cases, and for lining shelves with the objective
of decreasing off-gassing from exposed wooden surfaces. It has also been used
to create a sealed framing package and to create a low oxygen environment to
treat insect infestation. University Products has had the manufacturer remove
the standard red printing because tests have shown it may oxidise.

Marvelseal 470 is more easily heat sealed while Marvelseal 360 is more
puncture resistant. "

Marvelseal is available through various vendors inculding University Products.


Cheers!
Dave
