shaving the door handles

OK, all I can say is that if you have never used Panel bond then you don't know how good it is. Panel bond is not a filler like bondo or a gimmick glue. That stuff is tough and if not used properly you could easily end up being more work than if you were welding. If you have a MIG welder, than that's the way to go as it will be much easier than using panel bond and a lot faster. Panel Bond tends to run as it has low viscosity, and it takes a few hours to harden and at least 24 to fully cure. you will need some clamps and magnets to hold your panels in place while this stuff hardens. It is easier to work with if you have the panel (door, hood, etc) laying flat to prevent run off. This stuff is tough,and when I mean tough, I mean you will need a grinder to remove excess or run off material. If you are concerned about longevity or how good it will hold the panel or if it will even crack with time, consider this: Panel bond does not rust, or crack with extreme temperatures and it's very sturdy. Of course I don't mean use it instead of a good weld when it comes to 4 links, notching etc..
This is just for panels, like the name says. It can be hard to work with panel bond, so it's not that easy. But it all depends on the person using it. You can do a crappy job and leave seam lines etc as anyone with a welder could do the same. is up to who is using the product. I think what the guy meant by panel bond being used on fenders was rear QUARTER PANELS like I mentioned. Fenders are removable.

ya sorry i meant rear quarters and actually door skins and other panels that are non removable from your car but hey everyone has there own way. i personnally would like to see some one dolly a mazda door its hard as hell to get in to one of those doors to just do some small work. Not trying to start anything just saying and like I wrote evryone has they're own way of doing stuff. I personally will never weld a door again as that panel bond when fully cured is like concrete.

I welded the doors on my car and it still cracked when some stupid bitch hip checked it to close the door. SO MAD!

The ones on my 87 were done over 8 years ago and still no cracks.

Yeah problem was the stainless trim on the side of my car. When she hip checked it all the force went on that 3/4 inch strip right above where the door handle was. It flexed the sheet metal and cracked the small amount of filler there
