I need to purchase a plastic V notched spreader to apply an adhesive. The notches need to be 0.025" deep. I have tried looking everywhere and cannot find anything. If someone could help me or point me in the right direction your help would be greatly appreciated 
Maybe a tile shop or if you need a bunch get some laser or water cut.
Could you use spacer beads instead? Potter’s industries type I are .019-.024 inches
