Wayneburg,

Waterproofing for paper, IIRC there is a product sold by Campmor? called Mapseal? that has been favorably reviewed on these forums. I think that it is a liquid that you apply with a sponge. Its been a while since I last thought about it.

I also believe that there are aerosol sprays that will do the same thing. Musing here, I wonder if Thompson's Water Seal (available in spray and liquid form) would work well...hmmm <plans a trip to the garage to root around and find a left over can to experiment with this weekend.> I'll see about a test and report the results here.

There have been several conversations on the forums regarding waterproof paper, i.e. Write in the Rain and 1 or 2 more. These are purported to be excellent for printing with laser printers (both sides I presume) and I'm looking forward to trying this out. Cautionary note, since laser printers use a heat fusion process to dry / bond the ink to the paper, it is imperative that you verify that the specialty paper you plan to run through your expen$ive laser printer will not "gum up the works". Perhaps some of us have tried laser printing on such papers and would be willing to share experiences / paper & printer types used.
