A couple years after painting this car in the late 90's, blisters started to appear on the DS fender. The problem got so bad that the car was sidelined until recently, when it was decided to try and remedy the paint problem. After the shop stripped the paint, and wiped it down, a stain started to appear where the blisters were. It was determined that this stain is silicone brake fluid wicking it's way into the fender.
The area in question has been treated with Prep-sol, to no avail. The next level was an aircraft quality silicone remover, which does ok on the surface, but the stains bleed back up after a couple hours. There is also another product, we used, that is supposed to penetrate, combine with and remove silicone, but it appears to have 'energized' the stuff and now, it's spreading further.
The origin was obviously the master cylinder and the fluid has wicked it's way around to the front of the car now Anyone have any suggestions as to what approach to take on removing this stuff from the panels, so it can be painted. Is there anything you can use over it to seal it in?
Replacement of the panels isn't an option.
Any advice wiould be greatly appreciated... Mine is "never use silicone brake fluid"
