Rust Proofing

Rust Check Logo


Rust Check creeps into all hidden rust-prone areas including doors, fenders, pillars, frame members, engine compartments and cavernous undercarriage areas where the Rusties love to hide out.

Rust Check Rust Inhibitor is a light oil-based liquid that we spray into all of the body panels using existing or drilled , and Coat & Protect is a self-healing, non-drying undercarriage treatment. It's thick like Vaseline so you get an instant layer of protection from your very first treatment.

Diamond Kote is our rustproofing of choice for new (less than 2 yrs old) vehicles.

Unlike annual oil-based treatments, Diamond Kote is a premium rustproofing application that is a one-time application with an optional lifetime warranty (for qualifying vehicles).

If you wanna dodge your Ram pickup from been stolen look no further, DDF Automotive has everything you need. From sophisticated car alarms to tracking and recovery systems. Very professional, very good customer service, friendly people, explained to me everything well and gave me a reasonable price. Now I can sleep without worries. I’ve had the rustproof done in 2 of my vehicles at this location as well, I’m very pleased with their work .

I contacted DDF wondering if they could install a stereo for me, they were very quick to respond and set up an appointment for me right away, they ordered the parts for me extremely fast and just in about 4 days they were working on my car! Cheryl and Jacqueline helped me out through all the steps to be able to do this as soon as possible, and Eric was able to do everything in about an hour and a half for a good price, Thank you DDF!
