Hello all!  

The institution I work for is looking into buy enamel baked bulk shelving which 
requires a wood decking of sorts. My question is twofold: 

What types of wood decking are considered safe for museum storage?

And, whatever type of wood I use I want to seal it.  I have seen the comparisons 
of marvelseal to household aluminum foil, but does anyone have any knowledge if 
aluminum vapor barrier sold in hardware stores is safe?  For example I found a 
site called atticfoil.com which sells a solid aluminum vapor barrier with a 
layer of polyethylene scrim sandwich between two layers of 99% pure foil.  Also, 
whether I go with Marvelseal or this vapor barrier I found, should I paint the 
wood first to add an additional layer of protection?  Will marvelseal bond to 
painted surfaces?

Thanks ahead of time for all help!
