In my experience, it makes a ball with a "softer" cover ignore everything like a harder surface ball without the chipping issues.
Also protects it from sun damage and water spots. :p
Interesting.
I thought you were going to say something like, it reduces hook by closing the pores, AND I was going to say that polyester hook doesn't work that way. I'm glad we avoided that.
I never tried wax on a plastic ball.
When my original Blue Dot (hardness 88-92) started hooking too much even after re-polishing, I sanded it to 4000 grit, then sanded it with a White Trizact pad (grit: ~ 6000 - 8000) and then re-polished it. Then it hooked a lot less.
These days I use a T-Zone; I find it to crack the least out of any of the plastic balls. I tried the original Spare Storm because of its hardness, but it was far too brittle.
I hesitate to try your wax method because I depend on my T-Zone hooking a little bit to make some spares, like the 3/6/10, 2/4/5, 2/4/5/8 and some splits. I can throw it pretty straight when oil irregularities warrant.
Thanks for the tip, though.
