Thanks so much for documenting your project. I'm about to embark on the same mission on my "new to me" 1985 16 angler. I will certainly benefit from the information you've shared here. What did you find most effective to remove items previously bedded in 5200? Some bedded components on my boat appear to have been set into polyurethane or perhaps polysulfide caulk. I was thinking of using a flexible 6" drywall trowel, working back and forth by hand; or perhaps the scraper attachment on my Fein Multimaster. Later, Mike.
