Theres really no easy way to do it realistically.I would suggest using a dremel with a right angle drive with a drum sander. set it to a slow-medium speed and have a go at it. maybe even clean it up with a mini dremel steel wire brush attachment after using the drum sander. Its "ok" to sand or scuff up the fiberglass under the old epoxy as your going to need something good for the new epoxy to grab onto. After its all said and done your not going to notice anything different other than new rails! </span></span></span>
