Save Your Car From Rust


So you thought rust was inevitable? That car companies design their cars to fail in 5 years? If you’re ripping through salt and sand all winter, your undercarriage, fenders, and doors are on their deathbed pretty early, UNLESS you do some maintenance for $50 and a day in the garage. Let’s taco bout it.

Rust is a reaction with air. Water speeds it up. The answer is simple: we just need to seal it off.

What You Need

Buy this kit and this can of goodness. This is the stuff to save your day. You probably have the other things in your garage, but this is a quick list:

Don’t skip the rubber gloves. This stuff coats you like ink, and the only way to get it off your skin is with scotch brite or sandpaper.

What You Do

Don’t bother sanding down to clean metal, this stuff eats into the rust and seals it up like epoxy. Most reviews say they have better luck leaving most rust on there. Google it a bit if you’re unsure.

Ö Check me out using Mechanix Gloves, the rust juice soaked through and gave me black hands! Ha.

The biggest areas to check out are the inner-bottom edges of your doors, any seams in your fenders, and the running boards (where you would jack your car up).

When you have all your areas ready to coat, pour some juice into a separate container (in case you don’t need it all), and start brushing it on.

Whatever it drips on, it’s never coming off. so maybe drop some cardboard down.

I took off all my plastic trim, and found a couple of rust holes. After I cleaned and coated a couple times, I scuffed the coat with 240-grit sandpaper and smeared in some waterproof, fiberglass body filler.

Inside the Doors

After the rust-proofing is dry, you’re ready for the cavity wax. Same idea, except this stuff leaks into the crevices like water, then it dries up and seals everything off.

Find the drain holes, stick the tube of the cavity wax in there and coat it. It’ll drip all over, just wipe this stuff up with a paper towel. I let my doors stay open for an hour to dry.

That’s it fam! If you’re picky, you can go score some color-match paint. The mazda is phantom purple, just check your color code and order some online or have a store like Auto Value mix up a rattle can for you. Be proud, you just bought your car another 10 years.
