Update -- I was able to remove most of the Sudbury Sealant using a razor blade with a scraper handle and a small paint scraper. Then I used Goof Off for what remained and it cleaned up really nice.
I'd email support at Sudbury and they got back to me after I'd already finished the job. The recommended Toluene or Xylene (the main ingredient in goof off). Hope this helps others with similar tasks.

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? Thanks, Jeremy C&C 34-1 #041 Vancouver BC
