The shiny part is solder to close up the pinholes that appeared when pressure tested - my welding was not so great.

Just these two holes took about one hour to cut out. About 2 hours to get lined back up and welded into place. Then another 4 to 6 hours testing and soldering, testing and soldering again, then testing again. All this over a week.

8 hours at shop time of even $40 per hour, which is cheap in my area, would be $320. To cut the top off and reweld could easily double that cost.

When I start cutting the second tank I will take photos as I go and post as I proceed. Wish me luck. If I mess up on thsi nest one the tank is so bad on the inside i figure I dont have much to loose. I have already spent 2 hours flushing the mouse nest out of it. UGH. kenp
I can certainly understand your frustration. First open the tank. Cost 0. Then a true and reasonable evaluation of the inside of the tank. 50/50 chance it’s really not worth trying to save. Like you I am not a good welder so if you decide to go ahead let a good welder finish the job after cleaning
