Since we're on the subject; If I use Kreem to seal small rust spots/pinholes...what happens on the outside surface of the tank if the Kreem seeps through? Can it be sanded and painted effectively? I have great looking little tank that I want to use and I'm sure, from what I've read, that Kreem will seal it but I also want to paint it afterwards. The pin holes are right on the side where they will be obvious so how do you surface prep for paint if the Kreem seeps out?
I asked this question previously but I've lost that thread and don't remember if I got an answer or not. Sorry
