Okay, I spent 26.00 for a 200ml can of R. wax and took one of my Point Lobos prints that is Pt/Pl and wax the hell out of it. I got about nothing as making the blacks deeper. For all the work and cost it really isn't worth it. I did try it on a OHP negative and it did protect it but again not worth it. this only pertains to using Pt/Pl printing on Arch. paper.

PS my wood turning friend loved the present I gave him though.
