K Frame Question

A couple of years ago, I went to the local U-Pull-It to score the K-frame and a few other parts. The car was a total rust bucket that lived it's whole life at the beach.
After breaking a 3/4 inch AND a 1 inch breaker bar (using a 6ft exhaustpipe/cheater bar) I got smart.
I took a piece of vacuum tubing and slid the one end of it into a hole in the frame by each nut, wiggled the end onto the threads and poured some brake fluid down the outside of the hose and soaked each bolt.
Brake fluid is a great rust buster/ lube and 20 minutes later the whole thing was on the ground.
