Or.. locate a wet suit manufacturer and buy some of their trimmings. Cheap
and works well for the uses Leo suggests.

O Jeff I forgot, I also have used foam from a wet suit, I use it also
as a seal with my vacuum chuck, works great, you might be able to find
a used suit for cheap.
good luck
Have fun and take care
