Re: 1978 Glastron 175 HPV rebuild
You might have some luck using 1 of these Multi-tools, I used it to uncover all the glassed in nuts & bolts (on the inside of the gunwale) holding my rubrail in place:
It can be slipped under the lip of the top edge of fiberglass above the seacast & cut all along that top edge. Then you may have just enough room & blade length to do the same vertically from the inside of the boat. That may give you just enough separation between seacast & fiberglass to slightly lift the rear of the cap & finish getting the 2 separated. This does mean you've already removed the rubrail all the way around the hull, and removed whatever holds the cap to the hull.
Like I mentioned mine was thru bolted w/ T-bolts that were not visible from the exterior:
Once the rubrail was off, I needed to pull just a few screws from the exterior, remove a couple pcs of trim that were attached the same w/ blind & buried bolts, and then remove the fiberglass tape that was run around the entire interior seam of the hull/cap joint. To prevent damage I removed the thru bolts 1st, in hindsight I probably should have been more aggressive & just removed the tape/resin/thru bolts w/ a grinder all at once, and just replace all the T-bolts. I need to buy more T-bolts anyway, some were rusted/frozen & snapped despite my 'careful' (SLOW) method. I may end up using an entirely different rubrail, since it's thin aluminum only, no vinyl/rubber insert. In a few places I needed to run the multitool @ under the cap lip to separate some random resin that oozed into the hull/cap joint. But eventually:
