I have used Chrox & Ferox on 2 Balsa paddles 3"x8" about
I fully painted solid cover of each powder mixed with fine mineral oil
it doesn't take much only a few drops & it will cover the area quick
let it dry for 2 days then rubbed off all the excess, it was surprising how much actually came off
I use them as a post hone finisher about 10 laps on each .3 Chrox then .1 Ferox
this is my method used
