Not sure if this is the forum but I have question about the types of finish to put on wood. I have been woodworking for over 30 years and have tried lacquer, spar varnish, urethanes, Tung oil, and so on. Working with some wood such as purpleheart, padauk and so on. After time the wood will start to turn brown and loose it's original color. From everything I read it is because of the UV rays. Has anyone found a finish that will keep the wood original color. I read that spar varnish is suppose to work but reading reviews that it also falls short. I think that if you spend all the time making something with different colored wood it would be worth protecting it and to keep the colors as long as possible. If anyone has an input I would be happy to hear. Thanks
