I wonder if welding around the ding would work.

I bought some very expensive vacuum sealant that was supposedly rated to withstand the oven temperatures. Scotty put it around the metal-glass seals (where he thought the problem would be), but of course we learned much later that wasn't it.

If that was Vac Seal ISTR that some collectors debunked it as ineffective....I kinda want to find where I read that and see what grounds they debunked it on.
