I purchased some Clear Flex 95 from "The Engineer Guy" in GA on line. It turned to sticky goop when I used it. I have purchased this product from this company before so this must have been a bad batch... and they can't say I used it incorrectly as I had success before. I have sent two emails asking how to clean up the mess and asking if they would replace the defective kit. NO RESPONSE. It seems they are only interested is selling, not helping. I sent them photos of the stuff with the emails as well so it was documented.
