So I took the week off from work to
surf and work on Loretta. I began with the roof. Somebody in Loretta's past sealed the roof with an aluminumized mastic, the kind used for asphalt repair. NO BUENO!
It took me 3 full days to scrape and clean off that mess, just in the area around the vents, rivets and lap seams. I'm going to leave the rest of it there, nobody looks on top anyway :-P
I then painstakingly filled all the lap seams and every rivet with Captain Trolly's Creeping Crack Cure just in case. Once that dried I wire brushed the lap seams back to bare metal and sealed them up with TremPro 635 Polyurethane Sealant. I'm no pro at doing this so it isn't pretty. But I can guarantee it won't leak.
What you see here represents 4 days work. I bought some new "retro" vent hoods on ebay, they should arrive in a day or two. Meanwhile I started on the rear windows. Pulled the eyebrow and windows and discovered the original seals with a lame attempt at a repair. More scraping and wire brushing. Got the windows back in with Butyl tape, stainless steel screws and sealed the top with more polyurethane. Going to leave the eyebrow off for now so I can polish the area.
