Newb question (IMG:style_emoticons/default/av-943.gif)
Whats the best practices of gas tank resto? Pulled the tank, and the bottom has plenty of rust, but not really flaking. Ideas? You experiences? Heard muriatic(Sp?) acid + a bit of water for a few days does wonders.... |

I took mine to a radiator shop and had it "boiled out" (whatever that means). There are products that you can use to then seal the tank. Hey? I thought you knew all this $hit?

All for $200. Seems like a good deal to me, after looking at the time and PITA it is to do yourself. |

A radiator shop here in east TN quoted me $135 to clean and treat. So looks like there is quite a range as far as pricing.

clean it out through electrolysis, there are a couple of threads on how to do it here. fill up your tank with water, add in about 1 cup of washing soda - take a battery charger, ground to the tank & insert some rebar in the filler hole (insulated from tank) and attach your hot lead to it. I did this on a 10 amp charge and it took me several days until it was all cleaned out.
get the caswell 2 part epoxy tank seal kit I called a radiator shop and they said it would be around 200 for a cleanout and seal. the way I did it above was $63 |

I agree with the POR 15. Very effective and easy to do provided you prep it all properly. If you don't set up right you can make a hell of a mess. Great result though
