So it's autumn here in Ohio and i have a considerable amount of rust all over the front portion of my frame and some spots here and there on some suspension components.. My original plan was to bust out the power tools and use a steel brush and remove all the rust i had access to and coat it with that Dupli-color Rubberized Undercoating with rust inhibitors..

I have been doing some reading and i have researched a product called "CorrosionX" it's used by the military and alot of aviation/marine applications.. it seems to be some awesome stuff.. but im still not sure if its the thing for me.. i just cant imagine spraying sumthing directly over the rust and expecting it to be fine until the next application.. This product is said to be safe on moving parts as well as electrical connections and what not..I will link you directly to their website and see if anyone else has input on this product or has heard anything of it.

There are alot of moving parts and stuff that is around that will make it quite a task for me if i use the spray on undercoating and try not to get any on moving parts but at the same time be sure i do not leave any spots uncoated so as not to leave an area where water would have a chance to slip back in under the coating..

Any suggestions or tips or products anyone would like to put forth.. It would be much appreciated as I would like to get started and finish this task before the weather gets bad!

Also wante to add that this is my daily transportation so i will be working with a 1-2 day window of time from start to finish!

Thx in advance!

 

I don't know how in detail you want to go, but I can tell you it took me 2 days - long days - to do mine. I jacked mine up and removed everything I could - wheels/tires, sway bars, brakes & rotors (was changing them out at the time anyway), bumpers, etc. I then pressure washed the undercarriage with Grease Lightning. I used an air die grinder and about 10 steel brushes. Went from the front to the back. After that, I took a hand brush to get what was left.

I used 3M's undercoating in a spray can on mine. Then used Rustoleum's black (don't remember the exact name, but it went on thick) to paint the plastic, etc, and for touch up. It turned out great and has held up very good. Mine's not a daily driver anymore and this year will not see any water, rainy days, snow, etc, but last year it held up very well.

I didn't look at the link, but anything that says you can spray it on rust and it will work is not a product I care to deal with. I believe the cleaning and prep work always determines how good of a job you will end up with - no matter what the project is. If you are going to do, might as well go full out and do it right from the get go... Just my opinion....

 

i did took off only the tires and rims and did mine with a wire brush, hand brush, and 36 grit paper when needed. dont need to get every last bit of rust to "clelan metal", but you need the crud off and a solid base. i hand painted red oxide primer, then did the black rustoleum afterwards. 3 years and still looks good. i think i spent about 8 hours total.

 

red oxide primer is the way to go, and then the Black Rustoleum - BUT - the prep is everything - I think that if you can sand blast there, that would be the best way, but not sure how it would be to do that around moving parts, etc - but sand blasting is how we usually deal with surface rust, and even if it's pitted, but still solid, fine...

bare metal is always the best... then you know for sure that you got all the rust in that area at least...

 

I just picked up 2 quarts of RustBullet at the local Summit Racing for alot cheaper than i could have gotten it anywhere else.. I have read great reviews and this stuff and talked with some people that have used it and loved it numerous years later.. and u do not need to remove all of the rust either. If you have a chance check out this product!
