This is a really really strange problem I have been having. I make and sell ashtrays and they all take the same amount of resin. I always do a 1:1 ratio. I make sure this is done properly with my scale and I have never had a problem with the finished product coming out sticky. I have noticed that I have so many leftover “A Side” bottles and I pretty much have to keep running to the store just to use the “B Side.” I’m not sure how this is possible and has been very confusing for me. Any ideas?
