Tung oil or bona traffic( water poly?)??
My dad did us a huge favor. Took 800 sq ft of reclaimed maple gym floor and sanded and installed it. He had to rush a bit on the sanding so after the buffer pad we see a lot if chatter ( wave) marks.
I like tung oil for the true-to-wood feel, the ease of repair.
I like bona traffic for the color( maintain light maple color) and durability, less maintenance.
I feel that tung oil will help disguise the marks and bona might accentuate them.
