   Have you checked with technical reproduction firms in your area--that is companies that make actual blue prints?  They use a strongly concentrated ammonia in their process.

   Regular 6% non-detergent ammonia works just fine, it just takes longer.  Otherwise go the blueprint shop route if you can still find a small one.  The big shops use aqious ammonia in an outdoor pressurized tank so they won't have it by the gallon.

   We trained hard, but it seemed that every time we were beginning to form up into teams, we would be reorganized.  I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion, inefficiency, and demoralization.
