I'm going to be painting the engine tin ware shortly , does anybody use anything else other than hammerite , anything better ?

I had mine powder coated and then a ceramic treatment by a local vehicle detailer

I also had mine powder coated but at about £150 a set it's not cheap. Rustoleum is a good option for brush or roller, much nicer than Hammerite, and you can get any colour mixed and sent to you by Avenue Coatings, Slough.

Any decent quality spray paint is fine, Plastikote, Rustoleum etc.
