Okay okay, enough cruelty... I pulled the wood off and had a look!
First off, adding that bumpout really
stiffened up that side panel. I mean before it had some serious torsion flex, but now it's straight and stiff. Very nice effect. Second, it seems like the panel is very solidly attached. I used a small amount of force, and didn't hear or see any cracking.
Interesting side-effect you can see here. There were some existing holes in the side panel and the JBWeld oozed into those. Bet the joint at those spots is quite strong. I'm glad I thought to put plastic down under that, or I'd be sanding wood off the back of the panel!
But that does give me the idea that next time I'll drill pinholes between the two pieces for extra bonding surface.
As you can see, some spots came out really clean, and others the JB Weld ran like nobody's business as I was trying to apply it. So I've got some serious cleanup to do.
So if you're thinking of doing something similar:
1) Make sure you set a very flat surface underneath the bottom piece to ensure you get a flat join.
2) Rough up both surfaces well. I used 80 grit, believe it or not.
3) Degrease it and let dry.
4) Apply the JB Weld to the top of the bottom piece
to minimize runs and mess. If I'd thought of it, I'd have loaded it into some sort of syringe or squeeze tube like cake decorators use to get a nice bead.
5) Set the top part on and weight it down good. Don't touch or peek for 24 hours!
Looks like this got me a good strong joint.
1) Grind off some of the excess, which will be tricky because the metal is thin. Some spots, I won't even bother since it will be hidden inside the case.
2) Add body filler to sculpt the join. I've got an idea to use sandpaper wrapped around a piece of PVC to get a nice smooth curve. We'll see how that works out.
3) Prime and prepare to paint with the rest of the exterior.
Then I can start on the front-side panel window!
