I weigh the hardner and epoxy when i first open the package. Generally the hardner weighs 200 grams and the epoxy weighs 180 grams. So when I use it I weigh out 10 grams hardner and 9 grams epoxy
Thanks for the replies, I normally use an oring. However, most pictures Ive seen the megabass has no oring. And others are saying not to use one. So I thought I would see what yall are doing.
