Why no love for this GE roundie ?

Not all guns have enough tip mass to make chassis soldering easy. I keep an OLD 85W soldering iron around for the occasional chassis ground joint. The heating element on mine is bigger around then the handle on most irons, and the tip is fatter than my pinky....That thing will melt ANY solder joint, but you have to hold it there for a while to get everything in some cases.

If you are having problems doing the positive lugs then there is something wrong with your equipment or technique.
