New Finish for a Store Model Bat?

[BVC]

I have an early 70's store model Louisville Slugger (Powerized) that is solid, but was covered with marks, finish issues, etc. Since it's no more than a $25-40 bat, and I plan on hitting with it, I decided to practice my refinishing skills. I cleaned off marks with a magic eraser dipped in denatured alcohol, sanded lightly, then rubbed on two coats of natural Danish oil.

From searching other threads here regarding bat finish, I'm thinking a wipe-on polyurethane should be the next step. I want something strong, as I might hit with it - real baseballs, not the batting cage plastic ones.

Any advice?

It would be great to have an edit function so that we could wipe out threads that die on the vine.
