To remove the old sealant use a heat gun to soften it and a plastic scraper to get it up. Use heat sparingly so you don't damage the fiberglass. Once softened it comes up pretty easy. With the top cover out clean the old butyl sealant. Replace all the old steel hardware with stainless the same size or one size larger in diameter. If you have to drill new holes in the cover go slightly larger than the screw size so you don't crack the cover. When you screw down the cover pre-coat the threads with a bit of caulk. Once all the hardware is in place cover with EternaBond tape. I used 2" EternaBond roof seal around the top edge and EternaBond double stick micro sealant putty tape around the base. No liquid sealants necessary when using tape.
