I  wire brushed/drill type  my front backing plates and then degreased with
their degreaser.  Painted both sides of the plates as well as the exterior
of the master cylinder.

I let everything cure/dry for about a week while I rebuilt the wheel
cylinders inbeteween little league practices and hockey games and......

Reinstalled everything except the brake lines.  I figured I'd blow out any
old fluid remaining in them before hooking up the newly rebuilt system.

Hey duh..... the fluid sprayed all over the backing plates near the
connection to the wheel cylinders.  figuring I had POR 15 on them I just
wiped it off with a shop towel.  Well......   Now about a week later it
looks like the brake fluid was some sort of super paint remover. 
The POR 15 bubbled/blistered everywhere it got splashed with brake fluid.
The master cylinder looks fine except the cover which blistered all over the

Anyone else gotten brake fluid on POR 15 with similar results.  Maybe I just
got a bum can or something.  Anyway I'll be calling the POR people to find
out what's what.

I thought this stuff was chemically resistant.
