The underside is a mixture. The floors are almost pristine, having been undersealed by the factory, and have remained shiny and black. This must be because road spray stays under the wings. The wings need some serious TLC.
This picture is the nearside , showing some spattering, but also shows the limitations of factory applied underseal, (which extends into the spare wheel well - must be applied with the wheel removed because it's comprehensively black inside).
The sump is well tucked out of harms way............
I've added neoprene corners for the wheel to sit on, but you get the black picture clearly here:
This is what happens to the edge of the rear wing on pebbly roads after 12k miles:
I've treated it for now but it needs more work. The other side is not so bad because the exhaust offers some protection.
