rusty roof tear off

You all have the right idea, but to make the spot weld's on
the door side area's more accessible, it's easier to just remove
the drip rail section's on both side's of the car to gain more access
to them hard to get at spot weld's. And yes........ you can either use
MAP gas or propane torch with an ole wire brush, to remove the
lead in those seam's. Just try not to get the metal to Hot........ just
have some cold water and a rag avaliable to keep thing's cool. Good
luck with your project!
