I have a large wooden cart that our exhibits dept. made for me out of plywood and 1 x 4s. See image below. I plan to load the cart with a bunch of signs that need to be transported to another storage facility and they will likely remain stored on the cart. Would it be adviseable and possible to seal the wood with marvelseal rather than paint it with epoxy or shellac? I don't have a clean ventilated space large enough for painting. I've seen marvelseal used in crates and textile rollers but I've never actually used it myself. I also intend to pad the crossbars with ethafoam but the more I read, the more I'm convinced I should seal the wood. Thanks!
