I ordered TouraTech engine guards with the powder coated finish.
The mounting brackets came through in the original "stainless" finish so I sent them to the local powder coating shop to match the triple black theme on my 2012 R1200gs. It came out GREAT.
The all black theme is difficult to keep clean, but it looks good when all the mud is washed off. Black crash bars.
Here's my F800GS with the fog lights tucked inside the BLACK powder coated Givi engine guards.
So, The black finish is durable and looks good!
