My circa 1930 MBO (21' Sparkman and Stephens design #1) is a visual mess below deck and in the open cockpit. Over 80 years the boat has been painted, varnished, patched, and generally mistreated. Over the last few years I have replaced all the floor timbers and 9 frames. The replacements are all painted with red lead. The rest of the cockpit is a mix of blistering and chipping enamel paint. After spending the winter replacing 3/4s of the butt blocks and the aforementioned frames I don't have time to strip every bit of offfending paint out of the interior, but I can scrape it down to a fairly smooth surface. What I'd like to do is cover everything with an opaque but breathable stain that will make the book look clean and cared for but will not appreciably add to the accumulation of paint. In years to come when I have more time for cosmetics I will try to do a more complete job of stripping every inch (though the red lead covered timbers are just as they should be---I just don't care to look at them). Any advice? Products that will cover, etc.

Also, on some (perhaps mistaken advice) two years ago I sprayed the forepeak and aft under deck sections with "Stockholm mix" (1 part pine tar, 4 parts linseed oil, 4 parts turps) to help fill some pinhole leaks. It worked very well, but I now understand that linseed is a terrific food for dry rot. I haven't yet noticed any problems but would it make sense to spray those sections with a mild solution of bleach?
