Hope somebody's on the board this weekend! Need help!

Had thought there was an old thread about sanding Interlux Brightside Primer --- but maybe it was on the old CLC board. Anyway, can't find anything in the archives.

Need suggestions on sanding this relatively high build primer. Have one coat on my North Bay hull now. Hoping to sand it out tomorrow and get the first coat of Brightside Polyurethane on while the weather is warm and dry. Anybody have any firsthand experience in sanding this stuff? Dry --- hand or random orbital? Wet? The directions indicate that you want to achieve a translucent effect when sanding the primer. Should be ready to go Sunday morning, so any help would be appreciated --- especially if it's soon.

Thanks.
