dont refrig epoxy... for 1 it takes ages to harden and 2 it wont pour... usualy i use all my ca on the plane im on, usualy about 3 oz per plane but if not i just stop and stick a pin in the top, no tips no aceton ect... much easier... also, accelerator fums cause tip to harden so the less accelerator u use the better, makes for a better joint without it anyway...
