I have been using Minwax wipe-on satin varnish for years and I like it until about 5 years later when I start noticing that it is yellowing. Then I really don't like it. Not to mention it is now over $20 per quart. I am starting a kitchen cabinet project using natural (unstained) Hickory. I plan on using a wipe-on as I don't have a setup for spraying. I really don't want them to yellow out into the future. And I don't mind mixing my own concoction. Best I can tell, all I need to do is mix varnish with mineral spirits 50/50. But what non-yellowing varnish to start out with?
