I have several holes in my metal eavestrough. I have tried some so called
leak stoppers to no avail.

I was wondering if I took a propane torch and burned all the crud off and
then polished with a wire brush and then some acid flux and solder if it may
work Any ideas? I am assuming the eavestroughs are galvanized so I am not
sure if it would stick or not. Failing that - any ideas on a repair
technique?

Aside from these 2 or 3 holes, they are fine everywhere else.

thanks
