PB-Blaster is one of the absolute best penetrants. Acetone and automatic trans fluid (ATF) mixed together will penetrate rust also. PB-Blaster is what I have been using lately. You might need to get is going with a persuader, then spray some more so it will continue to penetrate. Give it a couple days of whatever product to penetrate the rust, with repeated applications of the penetrant.
