Rust Underneath My 996

[valley996]

I have a 1999 996 which was originally a New York and Ohio car. Needless to say there is allot of salt damage and rust underneath. Does anyone know of a way to stop or slow down the rusting. Also is there a way of repainting or coating some way. Thanks.

Has anyone used Rustdoctor?

What's rusted and how bad is the rust? Is it just surface rust? The underside of the car is already coated with Cosmoline and should've protected it...

I've used a product call POR15 on other vehicles - it works good but is kind of messy. Removing the old cosmoline will probably be a big pain. Might be more manageable if you do it a section at a time.

It is not allot of rust but there is a residue that looks like salt or chemicals. I have sprayed underneath by attaching my lawn sprinkler and letting it run, but I still have residue. Can I just scrub with Simple Green and treat the small rust areas?

+1 on the POR-15.

Use the original formula Black Gloss and it WILL stop the rust. I have used dozens of rustproofing paints and solutions over the last 40 years and this POR-15 is the only one that I have run across that does the job.

Follow the instructions on their website to prepare the surface before painting. It requires minimal prep (i.e., you don't have to remove all of the rust etc.,) but you MUST wear gloves and not get any on your hands or any other part of your body. Once it hardens, you can only get it off by abrasion. If you get it on your hands it has to wear off.

No connection to the company, but definitely a satisfied customer.

I think that the key is that it cures by drawing in moisture from the surface and thus seals the surface from further rust.
