Knocking Down Orange Peel

[thedink9]

I refinished the inside gunnels last year on my 23 with gel coat, applied with a foam roller. It came our great with a slight orange peel finish. I guess I'm looking for more gelcoat duct to injest, as I am thinking of knocking down some of the orange peel high spots, so the boat will clean up easier. My question is what type of sander / paper should I be using and is there any special technique (sander speed, etc. ) I need to know about. Thanks in advance for your suggestions. Rich
