Downriver, it's nice to have someone around who knows chemistry! Speaking of yellowing, I haven't seen any significant yellowing on > 100 baits topcoated with Devcon 2T. Some are more than 5 yrs old. 95% of the problems I see or hear about regarding D2T not hardening result from poor measuring or inadequate mixing - especially the latter. I mix it like crazy, until it looks milky with air bubbles, then add a FEW drops of denatured alcohol to help it release bubbles while I'm brushing it on the lure. No failures for a couple of years now.
