Yes, good idea. I used gloss black (because the car is deep black) so it is almost invisible. Sills, also top of rear bumper to prevent loading scratches, and I cut some little bits to fit in the door handle recesses to try and stop my wife’s diamond from scratching the paint. Useful stuff.I’ve used carbon effect self adhesive strips on all 4 sills since new - still there, no scuffs and wipe clean. Cheap purchase from a well known online auction site and contrasts well on a white car 👍
