Re: epoxy damage from brake fluid

["David Swingle" <dswingle@xxxx>]

I've never found ANY paint that is brake-fluid resistant. Even POR15. 
The only way you could treat a frame to be impervious to it would be 
to galvanize it.

This is harder than it sounds because you have to get the epoxy off 
first. The only effective way to do that is heat. It's impossible to 
get the epoxy off the inside boxed in areas without cutting parts of 
the frame open and then re-welding it. The galvanizing process will 
loosen any epoxy you miss and turn it into a globby mess. It will 
also fill in all the holes in the frame, like where suspension parts 
are attached and screws threaded in. It takes a lot of time.

Galvanizing has been done, there was a writeup on it in DeLorean 
World a few years ago.

Fixing what you have is a lot of work, but a whole lot less than 
galvanizing. If you are really worried about the brake fluid problem, 
change the master before it leaks, say every 10 years or so. A lot 
cheaper in the long run.

BTW - the epoxy that has been damaged will eventually harden back up 
somewhat but it will not re-adhere itself to the frame. May as well 
strip it off now.
