A stock maker I have known for a long time tells me that chips, rubs and other marks not into the wood on a WBY Deluxe can be touched up, undetectable, by spraying Varathane 66 into a small cup and using a fine artist brush to dip and paint the imperfections. Sounds too good to be true, but I've seen his work and it's flawless. Anyone know the ins and outs of this?
