Quoted from killerrobots:
Thanks, I wanted to get as many lines out now as I could assuming it would be harder in a week or so but I am ready to hang it up.
Its all about the die back. And whatever grade of finish you want.
10 weeks from now you will see more die back. Always.
Chris usually applies more clear to flatten it out again after 8 to 10 weeks.
This is how you get a mirror finish.
Oddly in the long run it doesnt matter too much due to ball dimples, scrapes and scratches.
