DPeet - exellent info, thanks for digging that out! It is nice to see someone has actually tested it and decided to use it for a finisher. It gave me the impression it was used for finishing fibreglass or something along those lines tho? Probably doesn't matter, it seems to work equally fine on wood anyways.
I guess the difference is that my scales were already sealed with several layers of CA and sanded between each layer, so they already were pretty flush. I did not rub it dry, and only used my thumbpad to spread the glue. I'll try buffing them and see if that can further enhance the shine.
Glad you liked the inlay
