I too use structural Acrylic 2 part adhesive. The one I use is very quick setting, 5 minutes and full strength in 2 hours. It is very good at getting a bond to epoxy, metal and wood. It is thinner than Hysol and should be used on parts that are reasonably close fitting. I have used it to secure fuel bungs in Fibreglass tanks. One of the best uses is fitting catches where it gets a good grip of both the plastic and the Fibreglass. It can be held in place by hand while it sets. The 2 parts are pink and green and it makes purple when mixed. I have used it to glue in formers and will really speed up the building time.

The downside is it gets hot when it sets, it is very smelly, not good for indoors, the wife will not like it. Do not dribble it on a painted surface.
We modellers tend to be very conservative and will not often try new products. The world of adhesives has changed a lot recently and there are many good products out there. I also use Hysol 9466 for general wood gluing. It is nice and thick and does not sag much.
