Hi folks, tonight I did my first glassing on the project. I added some fiberglass to the inside of the wing tips to provide the 1/8" build-up around the edge that mates with the wing. While working on it a few questions came up that I wanted to run past you.
What do you mark you fiberglass cloth with? Sharpies run into the fabric. A ball point just snagged the weave and pulled it. I ended up with a carpenters pencil. It was pretty clumsy, but it made a mark I could see without damaging the cloth.
I am using West Systems 105 and 206 slow hardener. My garage temperature is 83* tonight. I started by pumping 1 pump each into a cup that I threw away. I just wanted to make sure there were no air pockets. I then pumped 4 ea of the resin and hardener. I hand mixed with a popcycle stick for about 3 minutes. I wetted my work and got the layup in place in just a few minutes. I know that mixing the compenents creates an exothermal reaction and it can get warm. But when I checked my cup about 5-minutes ago it was 313* and solid. The mixure had completely hardened. I touched my layup and it is still quite wet, so I assume the heat had the affect of hardening my cup. Is this normal? I thought my pot time was going to be far longer than 10-minutes and I was certainly not expecting a 300* reaction.
