I get tired of all the fu@king comedians on here.
I don't blame ya. Bunch of Wankers that they are.
I like that new Hand Polishing compound. It's like, Whacks On, Whacks Off.
They call it Fap.
Just Google, Fap.com.
But almost seriously, I use a cheaper compound. Takes scuffs out as well as polishes. I use it on finishes, spot repairs and as a final on Poly finishes.
Scratch Dr. or something like that. It works ok but when I start spraying, I will also upgrade the product my final preps and finishes. It works on plastic or acrylic head light lenses. That type of thing.
Many Cue makers, whether they use an Auto finish or some other product, will use a Macguires car product as a final.
They also have a series of finishes that one would use one after the other. I doubt that you would need to go that far.
You could also ask in the Cue Maker Forum. Gotta think of it this way. An auto finish, epoxy, poly etc, no matter how hard they might be, can be scratched and dented. Balls get smacked into each other for years on end. The Poly that I use is mainly for Hard wood Flooring. I figured, if it can hold up to heavy foot traffic, it must be ok. So yes, Water Poly can get hard.
So obviously you would want to use an Automotive type finish polish and wax as a final. Might be a bit expensive but hey, Your Balls Are Worth It.
Spend tons of money on cues and maintenance, may as well look after your ball set in the same fashion.
The only other tip I could give you is, don't use Skamui Chalk on your balls.
