After having tried and tested most of the leading resin brands here in the UK over the past few years, I can say with certainty that the Ultra Bond range of resins are the best by far. Not only do they have great optical clarity and adhesion properties but they seem to weather really well and not turn yellow like a lot of the other brands do. Shelf life seems pretty decent also as they don't thicken up too much even after having sat around for a couple years.
You wont be disappointed with these resins.
