Thanks Fred, Dave and everyone else who provided insights from when they dealt with these same issues.

Dave — I got my old fixed windows (redone by the previous owner with 1/4” acrylic and Plexus adhesive) out last weekend. I tried a carbide cutting blade on my Fein Multicaster oscillating tool from inside the cabin to try to cut the Plexus out; the blade was shot after about two inches… the Plexus is very tough stuff. The thing I found that worked best was a sharp chisel from inside the cabin; the Plexus is a bit brittle, and once you break part of the bond, you can work your way around and get the windows out fairly easily. I then used the chisel to get as much of the old adhesive out as I could. Due again to the brittleness of the Plexus, this turned out to be the best option. I then used the triangular sanding pads on the Fein to clean up the surface. I’ll even things out with 3M filler and sand again to smooth and flat before getting out the VHB tape and Dow 795; I’m going to try that out this time, using the proper 3/8” CAST acrylic. — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( > On Mar 1, 2016, at 7:45 AM, Dave via CnC-List <[email protected]> wrote: > > In my window replacement project I've removed the old windows, most of the > old adhesive, done a fair degree of damage to the gel coat and created one > small chip in the surrounding fiberglass.
