Hi Peter,

You said

If you take a look at any of the links below (and there are very many more), you
will find information supporting my assertion. Oh, plus the fact that I have determined
by use that such PVA works as a size for myself.
I wouldn't expect any sane person to build a boat using Gelatine sizing as the adhesive nor would I use urea-formaldehyde/acid hardener glue as a size for gum.
It's all a matter of degree don't you think? There's waterproof for boatbuilding and there's waterproof
for gum. Maybe they used PVA on the Titanic..:?)
