Also, the Catalina directions call for dressing the gasket inside and out with silicone caulk. After spending a week scrubbing that nastiness off the frames, I just couldn’t bring myself to do it. Instead, I used a THIN coat of Dow silicone vacuum grease, which I keep on hand in my workshop, and which is MUCH easier to clean up. So far, so good. My work involves a lot of gas-tight seals (think space station air-lock sort of deal) and the biggest problem with those is people putting too much goop on the seals. A little (clean) dab’l do ya!
