Ok, I ran into a snag. My little radiator didnt like the caustic soda and sorta leaked all my fluid out... I should have known this would happen. No biggie right? I took the radiator out of line thinking that all would be well. I was pulling 30 amps at the time. So today, I get home and notice that my lid was not sealing anymore. Well, I took some solid steel bar and beefed up the lid so that it would be stiff and solid. I wil add some pictures for anyone who decides to use the same style box I used. It seals wonderfully now and I dont think it will ever warp again.
