I preferred the Poly-Etch and Poly-Etch W from Matheson Gas, as the shelf life and storage conditions required for the Tetra-Etch made it a lot more trouble to use. Near as I could tell, there was no measurable performance difference.
Matheson Gas Products, 61 Grove Street, Gloucester, MA 01930
I don't have the phone # for this facility, but you can call what I believe is the headquarters in Seacaucus, NJ at 201/867-4100.

Hi everyone,
If anybody have the fax number or e-mail address of the following
company please let me know. I am interested in getting more
information about their sodium etching/activating processes.
1. Gore & Associates - Tetra-Etch
2. Acton Associates, Inc. - Fluoro-Etch
3. Matheson Gas Products - Poly-Etch
If anybody have experience with these processes please let me know the
pros and cons. Thanks in advance.
Regards
T.G. Yee
