I think most epoxies are pretty much the same type of thing. If it was me I would bite the bullet and get a new set of masters so I could ride. One thing that could be done is to make a metal plug to cover the hole left by the sight glass and just check it once in a while. But for all the trouble it would take I would still buy new masters. I think they are made of some sort of pot metal or real cheap aluminum castings so solder or welding would be out. john
