sorry to hear that, I hope he gets better.
I too have been blocking, go my 2K on and begun blocking that. I realized tonight that I actually mixed it with 1/2-3/4 the correct amount of hardner...
So, I am going to block it out with 220, then shoot another coat (properly mixed this time), then do it again with 220 and then 320. Should get my paint this week, so with any luck at all, I should seal it and paint it this week.
