Anybody have any good techniques for removing seized stainless screws from an aluminum mast? My spin pole car is really stiff. I'd like to replace it but I can't get the cap screws off either end of the track. I've tried various penetrating lubricants as well as using a big screwdriver and a wrench for leverage. I've also beat on them with a hammer in hopes of breaking them loose. No luck so far.
Any help is appreciated.
