      Since (after some 200+ builds) I plan, for the first time ever, to use resin aftermarket engines on an upcoming styrene kit build and plastic-weld (aka MEK) bonders don't work on resin to styrene, what is the best way to attach underwing resin engines? Best bonder to use and whether to attach engines before or after painting?

      CA or 5 minute epoxy. Attach whenever it's suitable for your build.

      Epoxy. I'd attach them before painting so as not to mar the paint with excess adhesive (which can be cleaned up with alcohol before it sets).

      Depending on the join, either medium or extra-thin CA. If you want to attach before painting, you use the extra-thin in much the same way you use extra thin MEK glue; if you're painting first and then joining, use the medium as you would tube glue (just be advised it cures faster).

      It might depend on the paint used. Since I usually use automotive acrylic lacquers, I sometimes use 5-minute epoxy after the painting is done. This allows me to wipe off any epoxy that oozes out of the joint with a Q-tip dipped in Bestine (heptane, rubber cement thinner.) Heptane does not affect nitrocellulose or acrylic lacquers, and will clean up uncured epoxy without marring the lacquer finish. A caveat: Don't try this with hobby lacquers, like Testors or Tamiya! I usually wipe down my lacquer-primered model with this stuff before applying the finish color, too, as it evaporates very quickly. It has no adverse effects on styrene or ABS, either.
