howdy.
Last night we were welding pans in a 70 bug.. of course it started to fume a bit... then the tarboards started to melt....
Anyone who's done this tuff knows the inside of the car will get a bit smoky.
We put in a fan --- started blowing everythig around.
Stopped
Instead we put a wet/dry vacuum hose in the car top and pullled the fumes/smoke out.
Worked like a charm....
