Doing a test with the hammerite is, of course, a very good idea.
Painted a lot of metal frames (not the bicycle kind) with it recently. Brief was go quick with a roller because it was invisible in the end. That stuff wants to be applied generously with a brush so the solvents can do their thing.
What I am saying, will probably look great. Might take patience and skills.
