Having a poke around before the Pixie goes in for the MoT I noticed that inside the rear bumper around the mounting brackets what I had thought was a galvanised surface is now flaking off. So I suppose the coating was some sort of paint (maybe Hammerite?). The rear bumper is now showing quite a bit of bare metal inside and I suppose the front bumper will go the same way. As a new coating needs to be a bit flexible would it be OK just to spray inside the bumper with Dinitrol leaving the chrome on the outer surface untouched?
