I'm using DuPont's Aluminum Conversion but it doesn't work as well as
some
I've seen. I want a little better etch. Also it is too expensive.
Who
has a better source? The old literature speaks of a powder form
chromic
acid etch. Anybody know where to find it at a good price? Thanks.


I'm a lurker in this newsgroup, but thought I could add something to this
thread.

McDermid Inc. supplies Iridite (another brand name for chromic acid). It
is
available for commercial accounts only (Montreal: 514 745-7040). McDermid
has other locations in US (check the phone book or do a Google search).

Thanks, Squirrel, for all that most delightful information.
