Hi, I havee made a sort of mandala pattern out of plastic bottlecaps (from milk, orange juice containers etc) and don’t know how to join the bottlecaps. I would like to display the bottlecap mandala outside and was wondering whether I poured resin all over it that would be a good option. The plastic bottlecaps are about 15mm high (0.6 inches). I have arranged the pattern within a metal circle from a wine barrel that is 30mm high (about 1.2 inches). I live in Melbourne Australia, so we can have some hot days in summer eg 40C or 104F and winter can go down to 6C or 42.8F.
Thanks in advance
