My gas cap is stuck.  Previously, I lubed the lock and had a new key made.  The Lock/Unlock function was fine, but the cap felt like it was stuck/corroded in-place. When the cap is locked, I know it spins.  So, I locked the cap and with a small piece of wood using a hammer, I got it to spin. Unlocked the cap, and it still was stuck.  It would rotated about 45 degrees and then stop.  I used the piece of wood and hammer, and now it will rotated grudgingly but not un-thread.  Has anyone e
