Another reason for sandpaper to quickly clog is if the epoxy has formed a layed of "Amine Blush" on the surface. If the epoxy feels oily or waxy, it has blushed. I recommend waiting 24 hours for the blush to totally rise to the surface. Then you should wash it off using warm water and an abrasive pad such as a Scotchbrite pad. You can add a few drops of white vinegar or household ammonia to the wash water. Rinse off with clean, warm water and a clean rag then immediately wipe dry with paper towels.

As for sandpaper, don't use the ordinary garnet paper sold in squares at the hardware store. You need a good quality paper such as a Silicon Carbide or Aluminum Oxide paper.
