But, obviously I would like to repair it. Do any of you good folks have any suggestions as to repair material? JB Weld can stand up to gas, but tends to separate from the bonding surface when exposed to gas. I fixed a broken post by drilling tiny hole below and over the fracture, applied JB Weld on fractured surface, and used thin stainless steel wire threaded through holes and twisted tight to tie the two parts together. Applied JB Weld over fracture on outside of post. I said all this to point out that the post has held up great, but I can see a separation of the JB Weld from the post surface.
So, is there another material that can be used to seal a small gouge on the float that doesn't have to stand up to stress, but will seal a hole in a gas environment?
