I've been working on my PM for a couple of weeks now and I'm having a ball.  My sander and I are becomming very close friends.  I've learned a few things:  (1) wax paper will stick to the work piece but it does sand off .  (2)The lid from the cell-o-fill tub makes a very good template for the deck plate holes.  (3) bargan sandpaper from the dollar store isn"t really a bargan...neither are yellow foam rollers with plastic handles from the dollar store.  you get what you pay for.  (4)  The hardest part of building a boat is learning to walk away and let things dry overnight, I could work on this boat twenty hours a day. Just finished pre coating the bulkheads and seats, I expect to go "3 dementional" by the end of next week.  Cheers. Ted
