This is something that I’m looking at now as well. I have been speaking to a couple of local firms and they can all offer a service. For me I think I’m just going to get the tank acid dipped as its going for a full paint job anyway. However I’m interested in the treatment post cleaning. I have heard some interesting things about tank treatments, for example POR15 and there apparently is some discussion over it and or other similar coatings. Apparently the additives in the fuel can eat away at this lining and cause problems blocking the filer/ carbs etc, or the exact same problem a rusty tank can have.

The company I talked to today recommended not doing anything like that. They could strip and clean the tank and then would spray the inside with oil to protect it while it went for paint. After that a bit of petrol swilled around to take this oil off before use is what they suggest. Thinking about it a tank fresh from the factory does not have any treatment to it does it? Furthermore the company linked to above makes no mention of post clean treatments.

So my question would be should I treat the tank with anything post clean? If so what? If not why? I would be very interested to hear what people have used in the past and their success with that approach.
