The Final Touch To Your Gym = a Pro Look
Oil / Stain / Paint or leave raw .... as you like.
Use a brad or trim nailer to shoot into your wall pads' top nailer.
At ends, cut a 45-degree angle on both pieces to turn a 90-degree return into your wall. Remove about 1 inch of the nailer on the last pad with a oscillating tool or jigsaw before installing this pad. End your trim run with the edge of the Pad for a PRO looking finish.
