I agree with the practice of uncovering as much as possible and regluing, and replacing/redesigning when needed, even high-quality kits.
I have had 2 H9 Ultra Stick 40's, and have had substantial issues. Had to rebuild & reinforce the landing gear blocks and rear wing attach points. The gear would rip out under normal use, and the wing hold-down would detach with disastrous consequences.
On the second plane, I had an engine failure at takeoff and hit a small sapling at fairly low speed. My bad. When we got there, the wing had a small hole in the leading edge and a couple tears. What surprised us was the engine and firewall had cleanly separated from the fuselage. There was evidence on just one side (out of 4!) of any glue, and no triangle reinforcement. This plane has no hatch, so access up front is tough. I wound up putting in a new marine ply firewall, pinned on all four sides, glued in with Super-Phatic.
Shouldn't have to go to such measures on a higher-quality plane.
