: Without intending offense to anyone ...

: The specific problem with slow cures is that epoxy also reacts with water and
: carbon dioxide. The faster it cures the less it reacts with these
: contaminates and the stronger the epoxy and the epoxy / cloth bond.

: The general comment is ...

: I tell people that they need to test their techniques. For that I get some
: abuse. Comments like Eric's support my views of testing. While Eric
: noticed the failure, it is possible to do work almost as wrong and not
: notice it until you are where a failure is not acceptable. (If I epoxy in
: cold weather, I always do some testing to ensure that the result is
: acceptable.)

: I have told people that the books written on boat building are poor because
: they lead the builders to believe that there is nothing that can go wrong
: if you follow their instructions. Eric comment shows us that you can do
: everything right and still get the wrong result.

George-- This is the type of response we all like to see from you, Useful information!!!,thank you.

I always thought slow cure was a good thing and fast cure epoxy was weaker. Would it be true to assume that epoxies like Wests System that are fairly fast curing are much better than Raka or Mas slow cure formulas for wood-glass-epoxy boat building?
