Cold weather is good for grinding and cutting. You need to be fully covered anyway. Use a Salamander for heat when you are inside the boat, but never when you are using solvents. We want you to survive this! I have done non-skid, deck, core, and hull liner removal, and electrical install in the cold. I have done wetsanding and polishing in the snow. But I wait til 70 degrees for epoxy, glassing and paint. Use the cold weather to strip all the hardware. Get it ready. Then wait for Spring to repair and recore and rebed. You will love this boat, and it will reflect your love and love you back!
