Suzuki 2 Strokes

Hi again,
Just as a matter of interest does anyone know of a fool proof method of removing the old tank liner that is peeling off the inside of my 380 tank. The tank has had no fuel in for a good few years but as soon as I filled it up the problems started. The liner began coming away from the tank in great lumps with a layer of rust behind it. The liner has not softened it's just flaking off.
I've read online about a 3 stage approach which uses Caustic Soda, then Spirits of Salt, then Phosphoric Acid. The paint on the outside of the tank is good so I don't really want to damage it.
Many Regards,
Glyn.

MEK will dissolve the tank liner. You will have to do it several times until the MEK comes out clean. You can get a head start by putting a couple of cups of drywall screws in the tank first and tumbling or shaking it for a while. Dump the screws and mess out and then start with the MEK. MEK will mess the paint up. Put the tank in a garbage bag and make a hole around the fill opening and tape it up good. After you get the failed liner out you start with acid to get rid of the rust.

Cheers for the info,
The garbage bag is a great idea.

Glyn.
