I'm located in Dr Drews area and have used Flitzs' Gun Wax for years for conditions like high altitude big game hunting to low altitude Quail hunting. The warmest conditions I ever remember hunting in has been the 70s with the coldest being below freezing with rain or snow. I've experienced absolutely no trouble with this product. It's prevented rust and has never gummed up on me. However;I agree that 115 degrees and high humidity would test the mettle of just about any product.
