I frequently pour a bunch of epoxy in the firewall area and let the plane (fuse) sit face down overnight. And yes, the landing gear area usually needs some additional 'attention'. I hate it when mfg. use Lite ply for LG! Maybe they think we can grease 'em in all the time
Hardware - sometimes replace it. CG Pitts Monster had excellent hardware as does my H9 P-47 (150)....GOTTA JUDGE FOR YOURSELF!
