Perfect, you are the best, and again, thank you Steve.Actually if you were happy with the color there was no reason to sand off the minwax stain. It's too thin to have affected the wood. I wouldn't use the Watco if you plan to use the Waterlox. Watco is a mixture of linseed oil and varnish so it would further seal the wood. The Waterlox needs to be able to soak into the wood so it would be better to use it instead.
I think Watco works better on walnut than any other wood so perhaps you should use it there.
