panel under the master cyl is where it's peeling. It's the accumulation of 3 years of brake changes and mods. Now come on, there has to be something that at least resists it.

Por15 doesn't seem too bad with brake fluid. Looks like I spilt some when filling up the master cyc, as its all on the chassis underneath, filled it up ages before i noticed it (months). It has affected it, paints gone greyish and has formed a weird texture, but hasn't flaked off, even with a brush.

About the only precaution you can take is to hit the area with copious amounts of water (say, a bucket full at least) every time you have even the smallest brake fluid spill. The fluid absorbs the water and the large amount of water carries the fluid away.
