Paleoman,
I’ve used a Bear Grizzly since the early 80’s and yes the finish is very shiny. I’ve used various cloth limb covers that can be easily made from camo cloth. I’ve also used camo tape with good results. I feel this protects the original finish and when I’m not hunting with it I can remove them to show off the pretty finish.
I’ve not had a critter spook while using my limb covers.
Currently I’m using a snake skin set from 3 Rivers and I really like the Tamarack version too.
If it were mine I would not paint it or sand it. I’d just cover it.
