I think you can get Hammerite that you can paint stright on to a metal surface. Sure they sell it in Halfords.

Taz, don't do it. It'll be scabby in no time at all. Also, paint has difficulty adhering to zinc. There will be patches where the water will get through the paint, either because of bad adhesion or just wee bits of the inevitable damage. These bits will be sacraficial just like your engine anodes and the area will bubble up. The whole point of the galvanising is that it is sacraficial and it deteriorates gently. When you paint it, because there is limited access in these areas of damage the zinc gives itself up vigorously.

Been there, done it and certainly wouldn't do it again.



Edit: I see silversurfer appears to have had success. Your call.

Cleaned a trailer up 2 years ago with a sander then got it sprayed with an industrial micacious iron oxide (MIO) no breakdown yet but does chip, nice finish though.

That's wot I used on top of me galvanising. Used for painting bridges. Give it time, the rust'll get it. 2 years is good though.

Got mine done with 'airless' spray, as JW says good for bridges but like all when the water gets under it it'll start failing and look cr*p again
