They even built some large military boat and achieved similar savings while adding strength. Purported to be better than epoxy w/o the handling toxicity and print through. I will know more once my 28' cat is built using this resin, CF/Kevlar, foam and Airex penske.

Urethane is a pretty awesome product specially in adhesives !! AS a resin sure as hell will be different !!
Have a wonderful xmas and a better new year !!

Messing round with boats is fun !! the learning never stops ,even after more than 30 years there's always something new happening somewhere ! BUT somethings never change and some problems never go away and just keep reoccurring !!so moved into Composite Forensics , Now that something completely new !!
