Does anyone here use liquid photoresist anymore?  On a lark, I looked for
photoresist on Ebay and came up with this stuff:
http://advancedcoatingsinternational.com/prod01.htm

Unlike all the other spray-on stuff I've seen, this is available in the
US.  It costs around $55 a quart, is negative-acting, and cleans up with
soap and water.  I'm a bit leery of using presensitized boards because of
the cost and because I already have a decent amount of non-sensitized
boardstock.
