Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) Have you driven your CX today?

The Aero and CX chassis are essentially all aluminum with wood lining the inner face of the rear wheel arch. If they are anything like Tarka it is all covered by a thick layer of underseal.
The only point where salty water might get in is the bead between wings and body and I treat that a couple of times a year with ACF 50. The car was finished on 3 July 2013, so next year it will be 10, and has run 46,300 miles. There is NO evidence of corrosion, despite winter use.

Bottom line: in my opinion an Aero or CX chassis Morgan is no more likely to suffer corrosion than any other modern car.

If not dried off after washing, the front brake pads are prone to sticking to the discs.
