Liz - I'm definitely not SURE I want to do it, but I am sure that I don't want to keep taking the canvas down, putting sheets in between each panel, and storing under my forward berth only to put it back up when rain is on the way. I have those snap down carpets on my deck and I hate it when they get wet, but need them for the little one! I wonder if it's really the material the strap is made of that causes the scratches or dirt trapped between the strap and the strataglass that does it. Anyway, the strapping material I got is webbing made from polyester. Seems to work on the panels that alread have it on. I saw a tool that looks like a vice grip, but from what it sounds like it only attaches the dome cap part of the snap not the other "male" part. I may get it anyway though because it sounds like that anvil tool is a pain. I'll have to look at the snaps I bought. I think they're stainless, but I'm not sure of that. Thanks for the help everyone!
