POR 15 gets some good reviews. I bought a Starter kit to do some brackets on my old 4/4 but sold it before I did them. I still have the kit and will try it over the winter if the paint is still ok. It needs using fairly soon after opening the tin apparently as it sets really hard. The kit has small tins so no major loss if it is gone off. It comes with prep solutions too.
I bought it here......
www.frost.co.uk. Their Eastwood chassis paint is good too. Used it on the 4/4 rear axle.
Just remembered the Pepsi. Used it on the cast iron exhaust manifold. Soaked a Scotchpad in it and washed them down. It did take the colour back to a grey. Good old phosphoric acid!
