Hey HK, I know what you are talking about. They call it infinite density closed cell rubber foam, kind of the same stuff they make cheap handle bar grips out of. I have been looking for this stuff by the foot for years, every time I phone a foam supplier they just tell me they don't make the stuff by the foot? Phooey on that, now I know someone who has actually seen it.
I have a 20 degree lay back nascar style aluminum seat that I would like to custom fit to myself and I would like to make inserts out of this foam, the seat has snaps rivets on it that I could use to hold the inserts on with. If anyone knows of a foam supplier that sells it by the foot I would be extremely interested in getting some. Ideally I would like to get 1" thick stuff so I wouldn't have to layer it, but I am not fussy.
Has anyone heard of a supplier on the web or elsewhere?
