Gary — I’m going to be replacing the fixed windows on my LF38 over the winter. I’ve done the Plexus thing twice now (previous boat); this time, I’m going to try the VHB tape with Dow 795 approach, like Paul did on Johanna Rose: http://svjohannarose.blogspot.com/search/label/NewPorts.
I’ll be using 3/8” bronze acrylic with a chamfer to the outside edge. — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( > On Oct 21, 2015, at 12:45 PM, Gary Russell via CnC-List > <cnc-list@cnc-list.com> wrote: > > Hi Paul, > I agree that 1/4" is too thin.
