I use this particular brand https://www.ebay.com/itm/25-200g-Epoxy-UV-Resin-Ultraviolet-Curing-Solar-Cure-Sunlight-Activated-Hard-hot/192558431358?hash=item2cd5607c7e%3Am%3AmJD-PoN2EW7s5v80hz_F3BA&var=492671366421&_sacat=0&_nkw=UV+Resin+Ultraviolet+Curing+Resin&_from=R40&rt=nc&_trksid=m570.l1313.
As far as I know, it does not yellow. It is cured with UV Flash light or sun light. Curing with UV light will results in a tacky finish to the touch. Put it out in the sun for 15 minutes, and it's hard like a rock. Very little odor, just like 5 minutes epoxy.
I also have a can of this https://www.ebay.com/itm/Solarez-Clear-Casting-UV-Resin-Gallon/232860562944?hash=item3637923600%3Ag%3AX-8AAOSwg3FUbPxF&_sacat=0&_nkw=solarez+casting+resin&_from=R40&rt=nc&_trksid=m570.l1313
This one is slightly more runny. Curing is the same as the above, but it is very strong in odor. Must work outdoor. You can dip your jigs in this one, but I don't like the fume. I will not buy this again after it's done. It is also hard like a rock after curing.
The reason I like UV curing is the instant cure, so you don't need a rotating device. There is no mixing and no waste.
