I am working on my integra's front suspension, but 3 bolts are rust welded. My impact gun managed to get one off, but the others wont budge. I hit them so much that the impact bit got too hot to the touch. Sprayed with penetrating fluid, hit it with a hammer etc.
My only other option is heat, but the problem is, that it's a wheel well and it traps heat, not to mention there is a brake hose which is very close to the area I will be heating.
How can I contain my propane torch heat to this specific bolt without damaging other areas?
Barring that what about the mats that plumbers use when using a torch to solder copper pipes in the walls?
Whats that?

You can find it at big box hardware stores usually with the torches and plumbing supplies
Here’s an example of how it works

They do get hot… just very slowly.
