[SEL] semi- OTgas tank sealer question

[Don]

Best thing to use I have found is a handfull of dry wall screws put in the tank and shake it will dislodge rust and scale fast then you can find all kinds of sealers in Hemmings magazine there all pretty much the same thing you get a qt put it in and slosh it around drain it out let it dry and do it again it will seal all dust and junk that  you cant get out with your air hose ect dont flush the stuff out with water !!! you will have left over water in the seams and the sealer doesn^t like wet spots at all use something that will dry like gas or something that will dissapate by it self
