So I'm in the process of removing some of or all of the old gelcoat From the hull in the inside of my cabin and under the washrails etc. It's caked on there , cracking etc.. Sorry I forgot to take pics today. I'm using a small 18" belt sander and all though tedious it's moving along. There is cracked gel coat up front in the cabin and when you get through the first layer of it is tacky underneath so the belt clogs right up. Is there any other way of doing this? Sandblast? While I'm at it anyone have a good wholesale sandpaper website?
