Re: ARF glue joints, many times these have joints, especially in the plywood fuselage structure, where glue is applied to one side of a joint, leaving the other side only partly glued. Adding CA to these joints does complete the joint process. Also, thin CA can wick quite nicely into joints through the surface pores of the wood, especially where the all to common ARF glue (I don't know what it really is) just sort of sits on top of the wood. I can't think of any other kind of glue that can wick into existing joints like CA can.
Agreed.
That's the primary reason CA works so well for hardening and re-inforcing sometimes poorly glued ARF's, especially in hard to reach areas.
I'll also use a fuel proofing mix to get at more accessible areas too.
