I've used two coats of Hammerite Smooth on steel car wheels, without
any undercoat, as instructed on the tin. Okay for a year or so, then
the rust comes through.

For that application, Hammerite is the wrong paint. It is fine on toolboxes
or fixed metal objects, but not something that flexes. Hammerite sets to a
hard and brittle film.

Hadn't realised that - might explain why some falls off my bike's frame,
especially the rear triangle which I do bend a bit on hills.
I'll look for something else, perhaps like that on my Sunbeam motorbike -
could cuts slices off the undercoat on that!
