Jasco Premium and a heat gun
I second the opinion about Jasco Premium. A couple months ago I repainted the Sitka spruce mast of my (new to me) 1980 CL 38' Offshore cutter. I took the old paint and underlying varnish off with Jasco, after trying two other products with lackluster success. With Jasco it was remarkably easy to get down to pure bare wood, much quicker than the heat gun alone (which was good for random stubborn bits). BTW the wood and factory scarfs after 30 years were as if cut and glued yesterday. One small rot section at foot (8" x 4") was repaired by a local (Panama City Florida) boat carpenter. He epoxied a new piece of Douglas fir into a tight fit and it's stronger than the original wood (his bill? $200). This points up the fact that wood masts can be easily repaired almost anywhere, in contrast to aluminum. When painted, at least, such repairs are not visible.
