Now THAT would be great!!!! Something that can be sprayed
on with a "household" sprayer. AND, some kinda stuff that
would have a good shelf life.

Cary,

I found this information very good for etchant formulas but all of the
resists are non-photo. Got any homemade photo resist formulas?

Hi Andrew, here is a link to a pretty good PDF for "art" type etching. It
gives both etchant formulas and resist formulas. Knife makers and jewelry
makers use this and there are tons of other links in Google.
