Obviously the West rollers work fine. I just don't like all the air foam rollers introduce into the resin.

I now use mostly mohair rollers. Yes, short nap. You want a thin film. Like Bill said, most mohair rollers will have a cardboard core that is covered with a phenolic resin. It will be reddish brown in color. Some have plastic cores. Generally they will say on the packaging that they are good for enamels, urethanes and epoxies. Paints that generally have the nastier solvents that would dissolve a foam roller or cardboard core.

How many to buy: 1 cover per application should be more than enough. Seriously. When you roll, you're always introducing more fresh epoxy into the bristles. Any epoxy from the first batch will have been dissolved by future batches. Try the freezer trick. You MAY be able to build the entire kayak with one or two 9" coves cut into thirds.

I prefer rollers for applying epoxy. I've only had good luck using squeegees on flat panels and on exteriors. On the interiors it was tough to get the resin up on the sides. It always just pooled along the keel adding weight. I also only use brushes in areas that I can't roll. It's very hard to apply an even coat with a brush. My laminations done with a brush always seemed to need more sanding. Thanks to Rob Macks for setting me down the roller path. I use less epoxy and spend less time sanding when I use a roller.

Best of luck,

Dan
