other rust and body issues

The area I have circled in pic is brass that the factory put on there. Now I don't know how they did it. But it is there. Would like to know how they got it on there without it being hot. Curious???

It's the flame that causes the damage on 1980 and later sheet metal. The factory had ways of doing it without a flame.

Just curious about this too...how hot does propane torch get? I've read different things.

According to this, 3600°F.

Kinda warm. Hope the door jamb areas I patched do ok. The silver melts around 1400 f so I didn't have to get it to 3600 f . Seems like I read somewhere that mig gets to 5000 f and up. Both kinda warm. Thanks Jared

David,
I would definitely consider welding the roof on. If you're able to borrow a MIG. that's what I would suggest. I think it's a stronger weld than braze or silver solder.
The roof is where you need the strength. In the jamb area you should be okay.

It's amazing how much auto body has changed over the years at work I glue panels on and weld threw the glue with a inverter technology resistance welder that's a hybrid 10000 volts off of battery power the new thing is silicon bronze mig welding on seams because manufacturers don't want us mig welding anymore I hate late model collision and all the I-CAR crap I need to know. I think anyone can go on the I-CAR web site and look up procedure not shore give it a try

I am going to weld the roof on mr Jack. Going to try to use the pos harbor freight welder or try to borrow my cousin miller welder if he will let me. Plus I will have pop present for that job. Experience

David,
Try to borrow your cousins MIG with the gas. If you're not too familiar using it, try it out on some pieces of scrap metal.

Pop said that would be the best way to go to as the gas makes a much cleaner weld. Will do though.

Just don't do it in wind the gas is heaver than air and blows away then the weld is not shielded causing the metal to boil and pop or blow threw
