: I think you have answered a different question: how to achieve a super-clear
: layup over wood with typically one or two layers of glass. I was
: addressing a broader question of monolithic Vs non-monolithic layups.
: Suppose I'm building something with six layers;

I'm answering a question related to the way we build strippers and
glass a S&G boat. More than two layers of glass is overkill and excess weight.

My goal is a totally transparent, light-weight and strong lay-up for a stripper canoe
or kayak. This will work for a S&G boat also.

If you are using six layers of glass you are doing something totally different than I
am, so the person considering your advice needs to be aware of that.

The bottom line of the Gougeon Brothers research was that mulitpul layers of
glass, wet-out at the same time swell and absorb much more resin than single
layers.

: My main comment on the instructions you linked to was the lack of mentioning
: a bubble roller (aka: ringed roller, bubble-buster roller, finned roller).

A finned roller is not useful and not needed if my glassing suggestions are followed.

: Clean the finned roller with vinegar before the epoxy hardens. I prefer the
: aluminum ones, not the plastic. You can clean an aluminum roller with a
: torch if you don't hit it with vinegar in time. The flaming epoxy stink is
: amazing, so wait for a windy day!

Not needed, so you don't need to go through this.

The techniques you suggest remind me of past days when I worked with
polyester resin and fiberglass mat. A finned roller is needed in this application.
