I recently had detailed discussions with Tigger and decided to try Envirotec again. It has a much longer working time, but it is not as hard a finish. That can be disadvantage as far as getting lures completed, because the cure time is about 2 or 3 times longer. Devcon 2 has the advantage of hardness, but that can be a problem when it comes to tuning lures. The brittle nature of the Devcon can cause it to crack when bending a line tie attached directly to the nose of the bait when you are tuning the bait. Envirotec has much more flex to it even when fully cured and has less tendency to show hook rash on baits trolled at higher speeds for longer periods of time.
Therefore, envirotec will allow longer "pot life" but will slow the overall process of finishing a lure because each coat is thinner and requires more curing time between coats.
Overall, I'm going to stick with envirotec for now. It fogs less, but it more susceptible to dust boogers in the finish. It is softer but sags and runs easier. There are more tradeoffs than you can shake a stick at, but overall I like it better...for now.
