If It do not want any change to the wood's color, I spray several coats of Deft Clear Wood Finish,, I prefer "simi-gloss". It is Lacquer, so dries quickly, and several coats can be applied if a short time. I also spray it over painted projects. I have been useing it for ocer five years now. Unfortunately It is not available everywhere. I get it at My Home Depot. It is available online... WOW,, Amazon wants almost $24 a can, I have not paid that much for it but have not had to buy any for some time... At that price I will have to rethink it. Seems to me they are trying to price people out of hobbies.
