That worked well.

Great cheap solution, I don't think Halfords will be stocking this!

I have to do same but I'm going to use vinegar to clean then thinners to remove the vinegar Dry it out in sun and put in a tank sealer I have brought . Puts a layer to stop the rust again .

Hi Peter, yes I used a tank sealer on the old BMW I have. I thought i'd try this first. Vinegar is also an acid, so would work well i'd imagine.
