Hull sanding

[Christopher]

Planning on sanding the my hull this weekend (96 B2) after some minor glass repair and patching. Also, sanding the hood and the the hatch cover as well.

What kind of sandpaper should I use in the plastic? 320 then 500? Should it be wet?

What about the hull? 60?

Any feedback is appreciated!

Wet sanding prolongs your sand paper, prevents clogging.

Depends what kind of paint you use, but somewhere from 200-600.

As for prep for fiberglass work, I generally use 24-60 grit, on air powered tools.
