I have an old HF blast cabinet and am sandblasting a couple hundred UHMW parts to finish them.
On the far right is the part after machining, center is after sandblasting, and on the left is the finished part after treating with Trim & Shine. (an Armor All like product, but a lot less expensive) This process gives a very nice black matt finish on the part, and covers the machining marks and minor scratches.
