I thought it'd be interesting to see how long it'd take for the painted wheel rim to start rusting. To give me some idea how long a similarly painted trailer chassis would last before turning to a 4 letter swear word.
I stripped all the rust I could from it using a wire brush attached to my electric drill. FWIW I removed the dust left behind, with tap water. It was then left to dry for a week, before receiving 3 coats of Hammerite.

The rims are currently resting on a bench in my back yard, exposed to worst the weather can do.
The paint is already dry, so if you like watching it dry, this probably isn't for you.
