: I am contemplating using magnetic hatches on my Petrel. Does anyone
: know the gasket material that Joe Greenly uses for this? On
: searching this I ran across some pictures of his boats, it
: appears he uses some type of clear textured material, which goes
: directly over the magnets in the rim. Here is a link to the
: picture I found.

I think what you're looking at in that picture is the carbon cloth with a layer of clear glass over it, not the gasket. You can just see the weatherstrip channel around the inside of the line of magnets. I just use 1/4" weatherstripping on my magnetic hatches. As long as I keep the magnets within about 4" of each other it compresses the stripping just fine.
