Review on La-Co 11575: High-Temperature Heat-Seal Stik Epoxy Sealer Stick - 3/8 oz by Chad Michels

Works perfectly. I had a customer who brought in a microfridge which he punctured trying to defrost and had a hole in the aluminum coil just big enough to fit the tip of a pen. I cleaned the oil of coolant and paint, got a warm evaporator coil, melted it, tested it with nitrogen at 150psi, and it lasted and lasted. Vacuumed and loaded back. Let's just say that everything works fine and the customer is very satisfied. If you need it, don't be shy. It's worth it! This is how I can rescue an evaporator that has fallen victim to a flat tire.
