Hi all,

after about 6-7 months of inactivity, due to job/home/country change,
I am about to start on that gum thing again. I'm more than a little
alarmed though at having read the provious mails concerning the ill
effects of temperature and humidity, since I've just moved to
Singapore! This is "worst case" conditions for you.

The temperature here is above 30 C everyday, with humidity always
above 70%. While it is possible for me to do some operations (e.g.
coating) in air-conditioned rooms, I cannot do the whole process. I
therefore need as much useful info as possible on how much I should
really worry about coating the paper, exposing, developing (water
won't be cold either), life of chemicals etc.

Please give as much ionput as possible. I'll be happy to share my
experiences once I get started. A related question: if I coat my paper
and put it in the freezer, will it REALLY last a long time?
