The (original, soldered copper) water tank on our Stanley Model 607 has developed a small leak - nothing serious yet but annoying. Leak is not surprisingly tucked away well out of sight, might be the RH bottom seam on the tank.

Anyone any suggestions for fixing it - removal might be a rather difficult job so want to explore all alternatives before tackling this.

We had to loosen and raise the rear of the body of our 607 to get the water tank out. The top of the tank has been removed and the inside of the tank will get cleaned and have spray-on pickup bed liner applied. There are other tank sealers that seem like they would work equally well.
