Nathan, My boat has to contend with the corrosive effects of salt water. Over the years I've used a product sold at the marina, I think it is called something like 'Mercruiser Corrosion Block'. Works very well, holds corrosion at bay in that harsh environment. I spray it on every piece of metal I can. When I bought VIN 3579 ~18 months ago, one of the first things I did was to put it up on the ramps, crawl underneath with my heavy duty very sharp and strong dental tool, pry loose epoxy everywhere I could, then spray corrosion block everywhere I could. I repeat this at frequent intervals, at least the spraying part. Very little new loose epoxy. Visually this appears to be working well. I don't consider myself any kind of expert on this subject, have found feedback from some other owners on this approach to not be very positive, but at the same time have the feeling that this may be a reasonably effective approach. It really appears to do an excellent job with banishing the rust. You might do better with this, than spraying the rustoleum. Other owners - any feedback on this?

All of them center around the engine mount box. I had discovered some superficial rust in this area earlier and made a mental note to check it out, now I found that some of the epoxy chips off. The metal underneath is brown but not totally rusted through; I would say it is surface rust. Now here is where it gets interesting; the effected section extends inside of the frame box! None of the metal I can see inside the frame is severely corroded. I can not punch a screwdriver through metal anywhere on my car however I do know that if I left these areas totally unattended for there would be some serious hell to pay in the future. I plan to order some POR 15 to cover up all that I can. What do you wise people suggest I do for the inside portion? I suppose I can chip away as much as possible by sticking a knife in through the small access holes, then spray with rustoleum? I believe that my leaky otterstat caused this rust over the years as the car spent most of its 25 years in Arizona. Cutting holes in my frame for access is NOT an option for me at this point financially. I do not plan on driving in the rain. Any suggestions?
