: I have mis-mixed Raka before...I thought too little hardener was hard and
: brittle, and too much was soft and flexy...which seems counter-intuitive,
: unless I have it bass-ackwards.

I managed to mis-mix Raka slow on my first coat for the Sea Spirit hull. I mixed 1:1 instead of 2:1. I didn't realize it until the next day, but fortunately for me, it eventually set up ok. It was a bit soft for a while, though.

and ... Since my wife is probably reading this: Yes dear, I am much more careful measuring out these things now and would never make such a mistake on Your boat. Really!
