That's true Glenn. But there are loads of products out there that can be applied to keep the wheel surface sealed. As a last resort you can clearcoat the wheels after cleaning, if you don't like cleaning them every week.depends if you ride all year round
not very satisfying when there covered in rot ,water and salt marks every day
Nothing lasts on aluminum wheels. You would need to apply special etching primer first, this never falls off and grips like hell to aluminum and then you apply the paint over that. Just applying clearcoat or other paint straight on aluminum is a compromise, it will eventually just flake off no matter what.Even powder coating will fall off from the road salt, but it lasts a lot lkonger than clearcoat. Salt is the #1 enemy of wheels and engine casings.
