For your leak....you will want to detrmine where it is coming from. Cracked resivoir (I doubt), broken hose going from the resivour, Bad master cylinder. Once you have determined exaclty where it is coming from then replace/repair. As for the epoxy coating...POR-15 is the best solution. I had my entire chassis sand blasted of all the old epoxy and I painted my entire chassis along with all my suspension parts (including springs) and it's amaizing. For your touch up you can get a small can of it, a little goes a looooonng way. Scrape all the soft/wrinkled epoxy off and use a good degreaserto clean all the brake fluid off. The site where you can get it from is www.por15.com. They are located in NJ. If you have any questions on doing this drop me a line. Steve
