I think the change has to do with the fact that about 3 large companies own most of the R/C business and too much of that has been shipped to China. Why can't you buy Ultracote from Tower. Monokote has a built in monoply. Same parent company? We have Great Planes, Topflite, Futaba, O.S. and probably more, all owned by the same company. You, who have stated that the EPA is involved are correct in my opinion. I live in California and many good products have been banned here because the government thinks we are not able to use the product safely or correctly (granted some cannot). I buy many things in Las Vegas when I go there, because we can"t get them in California. I think I will be using Klass-Kote in the future.
