I'm restoring a 1989 bayliner arriva. I have to do major work on it. I removed transom and all of the stringers because of rot. I'm hoping to get some tips along the way starting with working on small but difficult areas. Before I start replacing transom and the stingers I need to prepare the surface in a small but difficult place located near the boat's rear corner to the left of the out outboard motor transom. I need to prepare the surface for epoxy to bond but can't get at it. My grinder disc can't reach it. Anybody have any suggestions?View attachment 201462
