Thanks fellas!
Yes Feline I sand back after every coat with Liberon 0000. I think I'll do it every other for a few more coats then leave a couple to harden at the and as you say.
I don't know what finish I'm after, thin but durable I guess.
Dave, have you had any signs of playing wear from the 3 coats on your neck? I think I'll end up with about 10 in total.
