I used a furniture marker repair kit I purchased at the Dollar Tree to give my Harbor Freight driveway alarm sensor a camouflage appearance. The package does say waterproof but the marker does come off with mineral spirits and it will scratch off. So it is not inpeneratable (not a word) as I thought. I know the video it a little long especially when I'm marking the sensor, also for the breathing into the camera ( its not the wind) so forgive me this is my first video.
