In the current MR (June 2004) there is an article on "Modeling a Pond" by Lee Vand Visse, an ex MR staffer (page 56-59). In the sidebar on page 58 , "Simulating standing water" he states Envirotex "...surface becomes milky after a year and it's more likely to trap air bubbles." This is the first I've ever heard of Envirotex becoming milky. I have three pairs of HO scale modules and each has Envirotex waterways and I haven't seen any evidence of it becoming milky. The oldest pair of modules is about 20 years old and the newest is about 10. The water is still nice and clear. In fact the simulated water on my modules is the one feature that receives the most comments when at train shows. One woman remarked "Look, he's put real water there". Others in our club haven't had the material turning mikly either. As to Envirotex trapping air bubbles, it certainly does, and this is well mentioned in the application instructions. They suggest either breathing on the curing material, or waving a propane torch near the surface. Apparently the carbon dioxide from your breath and the torch stimulates the bubbles to rise to the surface. Since most of my water areas were small, I just breathed on them, and you could see the bubbles rising just like in soft drinks. I guess all it takes is time to read the instructions! I find it strange that he suggests using casting resin for his water, as it gives off very strong fumes (mentioned in the article) which would quickly spread though your home. He mentions opening windows and having a fan, but that it took four or five days for the fumes to be gone. Seems to me this fault alone would steer most people to the no fumes Envirotex. I have no commercial connection with Envirotex, I'm just a satisfied user who does not like to see misinformation spread around about one of my favorite scenic materials. Bob Boudreau Canada
