sounds good, I'll be tackling it Monday. Grand kid's here this weekend. Ya know, I all most didn't grind on the boat last night but, I wanted to get a lot done because the kids were excited about me getting the boat fixed. Oh well. I know the hardware store by the docks sells that gp100, I'll ask about it in the am I only ask about the MOS because a guy here used it but I'd rather work with something a bit easier to clean up. I need this to be as close to perfect so it doesn't increase drag or leak.
