stuck doors!!

Took the air cheisel and gave her some good knocks, finally the mechanism got loose and door popped right open. LIke I figured rusted and not moving even with 3 days of penetrant and beating it with the long punch and good hammer!
Now for the window, its rusted shut too!!!!!! lol, and the other door!!!
The floors have rusted out, but I had 2 of these back about '95 or 6 and they were in same shape!!! Sitting out in Tx does not bother the frames!!!
Like said, last time this sucker was on the highway was '80!!!!
