Rust

Crawled under my truck for a minute and noticed this. Should I be worried? What should I do about it. I'm pretty sure I shouldn't have rust on my crossmember

 

Clean it up and repaint it.

And you should probably get that dirt out of the cross member also and anywhere else it's hiding. Dirt gets wet, holds water against your undercarriage and encourages rust.

 

I second what @DCSBFTMFW said. You definitely wanna get that dirt out of there... What's on the outside doesn't matter nearly as much as what's on the inside- they tend to rust from the inside out.
Would clean it all out and paint it.

 

I will definitely do that. What's the best way to paint it? ive never dealt with rust before

 

Grind the rust off with a wire wheel until the rust is gone, and touch up with Rustoleum, or equivalent.

 

it looks like you bottomed out and had the crossmember contact ground somewhere

 

Yeah probably bottomed out our scraped on something

 

I think That's what I'm gonna do. Thanks!!!

 

Clean frame with high pressure water let dry grind sand wire wheel clean. Hit with oil and grease cleaner a pre cleaner for painting slow dry not fast dry the paint guy will tell you.Use a rust converter then prime then paint.Oh yes this will take s o m e time!Get a good frame coating and you should be good.Ps rust didn't look that bad .

 

POR-15, the stuff is amazing. I used it on the undercarriage and intercooler brackets on my Cobra 10 years ago and it is still like the day I applied it. Its only weakness is UV radiation from the sun...

From the website www.por15.com
"POR-15® Rust Preventive Coating is a high performance coating designed for application directly on rusted or seasoned metal surfaces and will stop rust permanently. POR-15® Rust Preventive Coating is non-porous and seals and protects many surfaces from water, chemicals, salt, and other corrosive contaminants and is able to be painted over rust. POR-15® Rust Preventive Coating is an effective anti-corrosive and rust preventive coating that offers superior chemical resistance due to its dense, cross-linked molecular composition and non-porous attributes.

I have also used it to great lengths.But a Cruty rusty taco frame won out.It will get put now that I got a new frame on my 05.Not until spring got to leave the snow behind.Hopefully we will have a spring taco cleaning soon.

 

as delicate as these frames are you will have to take extra care of them. I wouldn't off road them, or even take them in the rain.
