OK, now that my Rube Goldberg tank cleaner has been running for about 2 days now the tank is looking pretty clean, at least no more big rust spots coming off. I'm going to let it go a bit longer and see if I can get all the surface rust off. I tried putting some WD40 in with the drywall screws, but that just melted the duct tape I had on the holes and the screws all came out with a mess of dark rusty WD40. So I'm polishing it dry now. I notice the inside originally seemed to be painted black as near as I could tell. No way I am going to get any paint in it now, much less oil resistant paint. I suppose I should seal it with Caswell's which means plugging that vent tube and the breather tube so it doesn't seal up the tubes and drip out. Anyone seal an oil tank with Caswell's before?
