    Fascinating reading about the bows.

    To the main question:
    How could you evaluate the long term quality of the product like epoxy? West was around for some time, there are boats both professionally and homebuild that almost as old as I am. How can I know the resins I get from some place that advertise the price much lower is good or not?

    Research. There are comparison studies, contact users of various epoxies, research the subject on this forum. Buy a small amount and glue some wood together then try to break it apart. Also the boil test.

    This is ultimately my reasoning I starting this thread. The info is there, but in 1000 different places, I think it's a worthwhile endeavor to put it all in one location.

    I've used West, System 3, and Resin Research 2000 ( more of a surfboard resin with some UV inhibitors.)
    So far I'd have to agree with PAR, they behave much the same. I will look into the stuff bateau sells, and I have had my eye on RAKA.
    I have been trying the film compaction method with system 3 lately, with limited success. I get bubbles under the film that seem to form a while after I squeegee it on. I will try the RR with a film next, just for giggles.

    Is that happening using SilverTip, or General Purpose?

    That's very surprising. Looking forward to the results with other epoxies, as SilverTip is one of the thinnest (so fastest to wet out and least likely to leave air bubbles) epoxies I have used.

    No idea what your setup is, but when I use SilverTip and have a hole in my substrate (just naked core cell), sometimes the SilverTip will drain out of the hole in the core, leaving a less than wet spot or even a bubble.

    This no longer happens to me, as I've corrected all holes in my core now before any laminating with that stuff.

    Hear hear :)
    My dad used that to build our garage trusses, stacked on the floor with 1/2" plywood gussets and weldwood. I think it was 1968.
    I believe the first couple of his boats were weldwood boats as well. Thanks for that blast from the past.:cool:

    Ureaformaldehyde glues similar to resorcinol glues require high clamping pressures and have minimal gap filling properties unlike epoxies.

    Urea and phenol (resorcinol) formulations have zero gap filling properties.

    I remember, the resin out of the joint was as brittle as hard candy :D
