Welding Aluminized Exhaust

Lol,..... i still have a Silver Beauty from the early mid-80's that We ran the balls of of at the independent shop i worked at. The switch body got broken & nobody seemed to be able to cough one up, so We got a new one, the owner let the stray go home with Me. New owner in '04 added a body shop, & a TIG about 5yrs. in.
