I am not familiar with Kramer's Best, but I see it has several fans whom I respect. I must check it out.
I have used linseed oil on exceptionally dried wood. It doesn't have to be messy, because you only apply it drops at a time. You rub those in until they are very warm from the friction of your hand rubbing. You will be amazed at how far they spread. You wait a day or more and apply some more drops. My opinion is if you are slathering it on, you're going about it all wrong. Another VERY, VERY important thing to keep in mind: You shouldn't have to wipe off excess, but if you do, spread your rags out flat on a concrete floor (such as your garage or driveway) until you can bag them very tightly and throw them in the trash. If you wad them up and leave them in a pile or an open trash can, they have a terrible propensity to trap heat and cause spontaneous combustion. They can and will burn down your house! I am not being overly dramatic when I tell you that. It's the truth.
I have also used Renaissance Wax on wood that is not so dry, and on metal, too. I first learned about it right here on these threads.
