Review on J-B Weld ExtremeHeat High Temperature Resistant Metallic Paste - 3 oz by Paul Bijeaux

You must not "hate" the application. Nothing for those who do not want to contribute to the preparatory work, scope or form of the application and assume that the product will come about by itself. Will not happen. Clean the metal with something strong like ammonia, or better yet, scrape the surfaces. Do not interpret JB as "leaf". They don't make a peanut butter sandwich. Mix it in a glass right up to the moment your hand starts to pull away from the bone. Apply the epoxy to the toothpaste like a line stripe. Unlike the JB REGULAR, this extreme high temperature version is water based and leaks can be easily cleaned with a tissue or cloth as if you were an epoxy perfectionist. WALK AWAY and don't even think about testing the product for 5 full hours. Then go back and apply heat with a blow dryer for 10 minutes or if it is an exhaust or manifold repair turn on the car and leave the repair area HOT. (ONLY after 5 hours waiting time). do all this for heaven as happiness with results. everything else will be pure AD.
