I went back and forth on weather to remove one of the end caps of the tank and decided not to. Working on the tank I got to the point where it wasn’t worth the time to remove what dents remained. This tank doesn’t need to be polished. Just needs a little filler. Wanted to see what I could do for the end caps. I aired up the tank and using a heat gun and my hammer, I began working on one end. Turns out that the only thing holding the end cap on was a little solder, just on the edge of the end cap. Apparently I got the cap hot enough that the solder let go. The end cap flew off, ending up on the floor, folded up like a taco. Don’t have a picture as I was somewhat concerned weather I would be able straighten it back out. The Boathouse repair took about an hour and a half. It’s close enough no one will noticed. Being that I now had one end open I began looking for something to use to straighten the cap on other end. The 2″ PVC pipe with a union and end cap, over a towel, worked well. The union and end cap were left over from a rear pinion seal install on my truck not too long ago. Now, having access to the inside of the tank, I wanted to work on the remaining dents a bit more before soldering the cap back on. There is a link to a video link for those who may be interested.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
