As I'm sure many of you remember from being 15, getting your hands on a welder and sheet metal can be a pain. So, my question is as follows: Can I JB Weld small pinholes and expect them to last long enough to not rust further until I get extra sheet metal? I am very well versed in fiberglassing, but I have heard if I try to make fiberglass parts of panels, they will expand to fast, and drop out of place from the original part. Is this true, and is there anyway I can stop this behavior?
