Skip; a quick Google search indicates that Osage will darken over time. Here's

>with time if it has no UV blocker
So... I guess it's the UV that does it and if you can figure out how to cut
the UV and still keep the finish clear so the wood shows through, you're there.
And no, I don't think an SPF 50 sunscreen will do it ;o)
I would think you'd need to go to ash or something else to keep the light color
and still have strength.
