The finish I used was two coats of Melamine Laquer which was thinned 10% for ease of application and ragged on thinly. It smells awful so I wore a mask and kept the workshop door open. The coats dry within a minute and were left to fully harden overnight. I then rubbed them out with micro mesh abrasive working from 1500 grit to 3600, with a final coating of carnauba wax to complete the job. This produces a lovely gloss finish which paricularly suits the Kingwood.
These are really useful little planes and the curly walnut was smoothed with ease. The tight mouth and the 52 1/2 degree bed angle ensured there was no tearout to the reversing grain.
This one is in Bocote also known as Mexican Rosewood (although not a true rosewood).
