Re: Quality gas tanks?
I used the JBWeld fix on my leaky studs over a year ago and it is still holding solid. Like the man said make sure it is completely free of oil/gas/dirt. Also get some 40 or 60 grit sandpaper and scar up the area around the stud about the size of a quarter or nickel. Build up a cone of the JB about 3/4 of an inch high. When I re-mounted the tank I used a strip of industrial strength velcro which does most of the holding and the nuts are just tightened enough to be for safety back up. The velcro is also still holding up perfectly.
