Undercarriage Protection / Rust

Anybody use any products to protect the underbody/frame? I know there are commercial treatments, but I have access to a lift, so if there was some kinda grease or something I could spray on there, it'd be sweet. Anyone

 

Sand it down and hit it with a good coat of rustoleum black paint. It is a pretty good preventative.

 

got the toyoguard package thrown in for free, which includes undercoating. is it worth a damn?

 

anything is better than nothing...right?

 

Sometimes...There's also the thinking that if water gets trapped behind the undercoating from cracks and rock chips you won't see the rust. I'd rather see it ahead of time and hit it with rustoleum like you mentioned.

 

Line-X ?

 

Carwell.

 

I didn't get the undercoating...read a couple good tips here on TW though:

- Use a lawn sprinkler and shove it underneath the car every now and then to rinse the salt/grime off
- When spring hits, go under your truck (lucky if you got a lift) and hit the rusty spots with a wire brush/sandpaper then paint w/ Rustoleum

This is what I plan on doing to prevent my frame from being ruined by rust.

 

I just got mine undercoated professionaly. In chicago winters rust WILL form. No matter how preventative you are.

 

Got mine profesionally done by a shop that uses krown rustproffing. Fortech will be a good one to ask. Did a great job on my truck.

 

You'll laugh but go buy 4 cans of WD-40. Spay the undercarriage good and drive it. This spring get a pressure sprayer and wash down the undercarriage. In the fall, pressure spray and hit it with WD-40. Repeat the process in the fall. It takes about 15 miinutes to spray with WD-40 and 15 minutes to pressure wash. It's that easy and seems to work.

The WD-40 eats rust, surface coats metal, and loosens dirt. I've done this for a year now and afte I pressure spay, the undercarriage looks great. In Maryland we've had a ton of snow this winter. With the snow came tons of salt and chemicals on the roads. I did an extra treatment of WD-40 just because...

 

Hmmm, I might try that. Makes sense... WD-40 might be a little thin though...

 

There is a product out there called ACF50. It is amazing.... It is what they use in aircrafts to help prevent corrosion and rust. It is quite a bit thicker than WD40 and it stays where you spray it. We use it at work to spray behind and under all the deck plates on the aircraft and every time we pull them up they look brand new. Our planes are 80's vintage and everwhere we spray the stuff its like brand new.... highly recommend. Apply it twice a year or so. Works great now where to buy it? search the internet not to sure of any vendors off hand but i am sure you can get it
