Dave:

You can buy teflon that is etched on one side and bond it with
a two part epoxy called "Chemgrip". These items can be purchased
from most plastic distributors. Hard anodizing can be "Teflon
Impregnated" which gives you a very smooth slippery surface. We
have this done by Luke Engineering in Wadsworth, Ohio.

Hope this helps:
