I'm not sure what the end result of brake fluid is because I didn't go that route. I brushed thinner on the panels outside in the sun waited for the paint to bubble up then pressure washed them at 2200 psi the thinner made a nice rough surface to apply the interior paint on. Even digging with a finger nail after it was good and dry showed no signs of weakness. I'm sure if you soaked them in thinner it would eventually ruin them but I saw no advers effects from my method. I wonder if anyone has painted the seats with his stuff? I was shocked at how well it adhered. With the panels and center console out its a good chance to fix your cup hold if its broken add or run amp/sub wires. I added rear subs that fit in the oem spots and added the bass mod to the door speakers what a difference very impressed with results.
