The Scammell trailer coupling mechanism was well rusted and in need of attention.

The rust was removed by wire brushing, rather than painting, it was coated with, Prolan, rust proofing fluid with some black Cementex mortar dye added to it.

Prolan is tacky after application, but hardens when polished, a brilliant finish is achieved, that can be recoated without preparation,for additional protection if necessary, in the future.
