Okie,

I did the bottom hull with a pneumatic this past week. I went like you, 600 hand, 800, 1000, 1500, 3000 with the sander. I will say the 3000 allowed me to skip heavy compounding and go straight to Finesse it to finish it out. Looks great. Once I used finesse it, then I used Collinite wax and was done.

I'm very pleased.
