Try 3M General Purpose Adhesive Remover. I’ve never found anything better for removing adhesive goop – including the residue of 4200 and 5200. You can buy it at any auto parts store that sells refinishing supplies.
Removing silicone is a particular problem. When I rebuilt my A&H hatches a few years ago, I sourced a purpose made silicone remover to remove the residue (Sikaflex won’t stick to the silicone). I can’t recall the brand I bought. Perhaps someone on the list can supply the name, or you can find it on a Google Search.

The PO sealed with Sudbury Elastomeric Sealant (silicon + polyurethane formulation) and screws through the acrylic, which I've taken off using a multi-tool scraper. The sealant remains a mess -- the heat/friction from the tool seemed to soften and smear the black sealant. I've been trying to source some marine debond or adhesive remover that will play nice with fiberglass. I did find some Xylene based Auto General Purpose Adhesive Cleaner (PF600) which looks promising but has a "Warning: ... not recommended for fiberglass..." Any tips for removing the old sealant?
