Sanrenmu LAND 910+ and 9104 Carbon Fiber

So I've decided to put the single front scale that I made for my SRM 910+ onto a SRM 9104
 and made a pair of scales and a pocket clip for that SRM 910+ from carbon fiber

The shiny scales were made from a wheelchair's wheel protector, the bent clip was made from the same orthopedic stiffening material as the 9104's front scale

I'm still looking for a way to give them a more matte finish without getting sanding stripes
Bead blasting would be interesting as acetone won't do anything to them as opposed to the 9104's scales
