Part 1:
In a presentation on vacuum chucking, David Hout told of how he had tried several materials and now recommends synthetic chamois (non-perforated) as a seal material. The chamois was impressive in the way it would take an indentation at the area of contact when the vacuum was engaged, making a very solid mount against the chuck body.
I went to several auto parts stores looking for this material, but all I can find is some new blue stuff which is packed in moisture and goes stiff when it is dry.
Anyone know where I can find the older style chamois?

Part 2:
If it is no longer available, I will go with the standard, neoprene. Where is a good place to buy some thin neoprene.
TIA!

Cheers,
Kurt
