I used Huskers potion a couple years ago to free up all the nuts and bolts on the suspension of my car that came from the east coast USA. Took 6+ weeks to get things loosened up enough not to break any bolts or make the fix even worse. I did also us a little heat now and then. I know when it comes to getting things done on our mistresses, I'd like it done right now. But I try to fit it in between life's challenges. Sometimes we need to sit back and as the kids say, "Chill".
No disrespect to your end goal or time line. Just my new 3 cents worth.
