The product got some bad reviews. I assume you liked it...are the complaints at Amazon... on target?
I've used 4 Brands (including the Permatex) with good to excellent results from all. You must follow the printed instructions. There is a review where it worked well, but they admitted there was prep time needed and cleanup time. People in a hurry should pay to have it fixed. Plus you know some men don't read instructions until after it doesn't work. LOL
