Many years ago the old man had some steel Ford wheels powder coated. Within 12 months they'd started to develop surface rust around seams and edges. Years later I made some enquiries into powder coating and although it sounds like a good idea, I've been told the surface is porus and as a result, it won't protect the material underneath from corrosion. Based on this info, I'd rather use paint than powder coating.... Is powdercoating more durable to impact damage than 2 pack? Thoughts, opinions or experience anyone??
