Fertan is good. Some like jenolite or dinitrol stuff. All good. Hammerite good for very mild surface rust but nothing more than that. Wire brush and degrease first.
Its looking like Fertan then, I'm planning on attacking any light to medium rust areas with a wire brush and then a rust treatment, covered by hammerite or some such thing. On initial inspection, the car seems to be surprisingly rot free, which is why I bought of course, the rest of it is a bit rough tho
Thanks for the replies chaps
