I use a roller sleeve specifically designed for epoxy and other resins - it's a very short-nibbed, nylon bristle roller called a FIBERTEX (or FIRBETEK) - comes in regular roller size. but can be easily hacksawed to fit any roller. While I use it as a one-shot, it can be held in acetone between coats if you can stand having acetone around. It doesn't shed anything, soak up resin, or tend to lift things, and I think the short bristles help lay glass tape by penetrating the tape's weave. Manufacted by PINTAR, costs about $4 per sleeve here (Newfoundland.)
