Usual Caveat: These are my own personal opinions...
Resorcinol is a 2 part glue, one part powder, one part liquid.
It is best used in some type of enclosed environment.
Marinette Marine and Peterson Builders in Wisconsin, USA used it extensively in the building of wooden mine sweepers in the early 1950's in the fabrication of White Oak laminated frames.
The glue takes a goodly amount of clamping pressure and proper temperature to set up.
It got a bit of a bad reputation when it first became available to the general boat building world. Folks did not take the time to read the instructions fully or just didn't read them at all.
A number of significant failures happened with White Oak in particular.
Weldwood Plastic Resin is a creme coloured powder mixed with water to a creamy consistency. It requires a temp above 65 or so F. degrees and HIGH clamping pressure.
White PVA should never be used except for light household repairs or temporary items.
It is not waterproof and it creeps under load.
So called 'carpenters glue' is a variation of the original formula modified to improve some of the poor working qualities of white PVA.
Mr.S. is doing an emperical testing of some newer adhesives mentioned in at least one thread over on the WB Forums but, the results will not be available until sometime in December.
I have used both Resorcinal and Plastic Resin with success in both boat building and out door furniture making. I am quite sure I mentioned here in a previous post on glue, some out door furniture I made out of Redwood for The Sonoma Cheese Factory have been in continous use for over 30 years in Sonoma, California, 7/24/365 using Weldwood Plastic Resin Glue.
There are a number of more modern adhesives that I have used in small quantities but, I do not feel qualified to speak yea or nay about them.
