stuck doors!!

Yes, I did the hammer/punch deal also.
I will go to Amazon and order some Kroil. With all the bad rust in New England, I figure those guys understand what works!
I drug home a 77 Volare wagon from the dry Tx Hill Country coue years back, got it for the perfect grill.$500 complete rust free n running wagon. I took me quite a while to get the floors open, latches worked, but..they were stuck at the door weather striping, like super glued together!!!! lo

We used kroll when I worked for the city of Tulsa , it never showed me anything special , except expensive , always thot p b blaster worked faster -----------------??
