WOW ! you got your question out before I could clean up my answer!Yes, I would say that if you can bite into some solid wood you have nothing to fear. The trick will be making the plugs flush with the back side of the plywood, so the blind nuts have an even foot hold. If you have a razor saw, you can slice the dowel precisely the thickness of the plywood. After you push the plug in, then hit it with thinCA. Let the CA dry naturally so it has a chance to soak into as many wood fibers as possible. If you have any odd shaped repair work to do, make a pile of fine saw dust, pack it into any crannys, then slowly wick thinCA in, and get your nostrils away fast! It sets up like concrete, so do as neat a packing job as you can before hitting it with the CA. GOOD LUCK!
