hello, seems like most pple here have recommended a lot of good mths, wetting agent works fine without squeegy far as I can testify myself.
water marks won't really hurt that much, it usualyl don't show up on prints. unless it's those kind of mother-of-all stain.
on the contra, dust are more pesky. look @ it, the more ya wash ya negs and have to leave it to dry. the more vulnerable ya're to get dust sticking on ya negs.
good luck.
