RWM’s Core Coat is weather tested and can protect iron and aluminum cores against corrosion. We have been performing a test on 3 of our wheels. One had our core coat on it and the other 2 did not. We left them outside for for almost 2 years in all weather conditions and this is the result so far.

The core coated wheel is still in great shape. In the past year more rust is apparent on both the non-coated wheels than was present in the prior evaluation.
