it would help a little reinforcement and reduce flex
resin by itself will not reduce flex. you need to add mat to resin to get any kind of strength at all. Resin by itself will do a couple things; help seal the wood, if sanded it will smooth the wood and can make it easily paintable. If you are adding resin only to add strength, you ain't doing it right!
Thanks, I guess ill be adding mat because I really need the strength!! Thanks fellers!!
