Glue question

Anybody know of a glue that will stick wood to plastic or plastic to wood and make a STRONG join?

I'm working on a project where I've decided to make a wooden plug to extend a fuselage but I really need some means to make sure that the plastic sticks to the wood strongly.

Both will hardly bond well, so you cannot use normal polysytrene glue. IMHO, a super glue gel would be the best choice, because it holds on both materials and fills potential gaps, of you might try (if there's enough room) to bond or support both elements with 2C putty.

I've done this in two steps:
1. seal the wood with wood glue and/or filler.
2. use CA glue to glue the wood to plastic.

You can probably use the CA directly, but make sure you apply enough of it because the CA will be absorbed into the wood.

Be careful as well, because the heat of the CA curing can set the wood ahad.   Or smoke at the least.

Resin glue would work, also there are some all-purpose adhesives that work well. One that I use for multi-materials is available to the Railroad hobbyists as Walthers' "Goo" its very reminiscent of a product called Shoe-glue. This bonds pretty much anything. There are drawbacks such as it reeks of acetone when curing, also it really never 100 percent fully cures, so it should be used where the bond will be hidden and not be a part of the surface, as it may not paint-over well.

Two part epoxy would give you a good strong joint. It's just a bit of a pain to mx and apply of course.

One of the medium time setting ones would work best, the 10-15 min versions in my experience. The 5 min ones get a tad warm and you need to rush along sometimes.

my father in law swears by soaking the wood in plastic weld and then clamping the plastic on, then add your covering veneer, its how he adds brickwork to the tunnels on his railway layout.
the things you learn, give your mind the wings to fly, and the chains to hold yourself steady
take off and nuke the site form orbit, nope, time for the real thing, CAM and gridfire, call special circumstances.
