Hi. I've noticed that where my knees grip the tank on my SP2, the paint is dulling

- guess I'm slowly damaging the top lacquer / top layer of paint? I can recover the paint with a black coloured polish, but long term I'm thinking the dulling will get worse and worse.
I've bought SP2 specific stompgrips, but am not sure that they'll look very nice, so haven't yet put 'em on. Also thinking of Motrax strips and dots or the clear sheet they do, but not sure what way to go.
Anyone use any of these or similar protection? / any advice would be much appreciated.
Cheers,
Hedge.
