Keith... is your mylar glossy? Remember what we figured out a while
back... if you get newton rings with it, you can spray it with a fine
coat of clear spray, like Krylon brand or artist fixatives. Don't use
something that's made for outdoor use 'cause it will have UV blockers.
That may keep you working until you get the Kreene.

I pulled the frame apart and replaced some old foam rubber that sits
under the ribbed bed of the frame with some nicer neoprene. The
pressure remained the same throughout - at least on the dial, but who
knows? While I wait for my roll of Kreene to arrive I tried using a
thin (1mil) sheet of Mylar as you would with Kreene. No more contact
problems - at least for now. I'll run some more tests tomorrow just
to make sure and keep you updated.
