Hi Dan, call yours non scientific , when i did my testing i just dragged around weighted panels painted in a checkered fashion (so the same scratches would span both graphite and HBN) on the driveway, gravel etc and i didnt find any difference, but i practically already had made up my mind on the HBN when i posted about it in here since its an industry substitute to graphite and they MUST have done some testings first, who knows how long ago, but still...

On the coverings coat with varnishes etc: try mixing the HBN powder to those too, there should be some benefits in that too.

: You'll be glad to hear that I finally ran my little not-so-scientific
: abrasion test of the hBN. I tested it with 5 other opaque coatings and 6
: clears. In my little test it appears the hBN performed exactly the same as
: the West 423 Graphite. Impressive. It needs full-scale testing to really
: see how it performs in the real world. The next kayak on my build schedule
: will be used as a testbed. I'll also be coating my own Guillemot with it
: for more testing.

: Stay tuned...

: By the way I also tested a few other coatings. 12 total: 6 opaque and 6
: clears. All were marine or commercial in nature (no hardware store
: brands).

: The two-component urethanes (clears and colors) performed much better than
: the single pot paints and varnishes. Not really surprising. The best
: performing clear was actually an automotive urethane (DuPont ChromaPremier
: 72200s with flex additive). Stay away from the waterbornes... Again, not
: surprising.
