Kevin,
Resin with a 5:1 mix ration makes my skin blister on contact
while 2:1 does not seem to affect me.
So now I use 2:1 and try not to make contact with it.
Possibly resin infusion may help downstream.
The idea of kitting out in a complete hazard type suit to build is not that appealing but I have read articles about people going that far to build their dream boat.
Regards,
Phill
