What do others think?

Paul... I have seen it used in building larger boat cabin walls and such and thought it was pretty neat way to do it. They laid the first layer of glass cloth down on a big table with a slick surface sprayed with wax, then laid on the foam core wet on the contact side, then glassed the back. They could make great big panels this way. They were building 32 foot oil rig tenders and fishing boats. Kinda expensive process though, I think.
A few years ago I helped build some rather large beer coolers for a bar and we used that method. These were 4' x 8' open top beer coolers on 4 x 4" legs for icing down a
bunch of bottle beer at one time. We used foam insulation board with aluminum on both faces. Just built a big box and laid on about 3 layers of glass fabric and resin. As far as I know they are still going strong 15 years later.
Now, I think, you can buy panels already fiberglassed... Prolly expensive, but sure would be light weight. Nice looking tears they are building even with the bare bones galley.
