This was on another forum but I thought I'd share. I use a lot of glue due to my kids breaking everything. In the past I've used the expensive tubes of Epoxy and ran out of them quickly. The Epoxy I bought, after a tip on TV forum, was the one below. It comes in two 500g tubs. Cost from builders supplies was about 240 Baht.
I use tooth picks to mix equal parts of each and Bobs yer uncle. Full curing time is 72 hours on the instructions, but if not under any stress it can be usable before. Great value compared to the 30g tubes. If you want the clear epoxy make sure it's printed on the tub. Otherwise I think it comes in other shades.
