Ok, I'm a little confused here. I thought the recommended epoxy for doing engine mounts/wing joints fuselage doubles on a profile was a slow set epoxy, but when looking at my local hobby shop or even online all i am see is 5 min,6 min, 15 min,30 min aqnd 45 min. Arent there any epoxies in the 2 hour range ? Please be specific to product so I can get the rightn thing.... Thanks in advance.
