Surprisingly defender hood isn't sealing well, lots of dirt / spray is going straight at engine cover and to the back.

 

l have sprayed every exposed metal part/suspension part/bolt etc on my Defender with XCP
Which is a clear wax type coating designed for motorcycles
Any proprietary clear "anti corrosion" wax spray will work.

After a U.K. winter of salt on the roads and the Defender used daily everything still looks new.

 

[QUOTE=CEHansen;862676]Tested today with a magnet, didn't stick to the inside or outside.
So the hood is full aluminium.
