Ive been using JB Weld for a very long time. I can tell you that this will fix just about anything. I even fixed a cracked plastic resin tub with it and a Fiberglass tub and it held. Then painted it with white porcelain paint. Ive fixed auto parts, desks and power toools. Ive made bolts and pins with a reverse mold (form). This product is great for the things I cant get too or things I cant use my Mig Welder on. I like the original set JB weld with steel reinforced because it has the highest strength rating out of all the JB weld products. Ive used JB Quick and it worked ok too for the application I used it on..
