Im thinking of undercoating my 7. not because I plan on running it in the snow or junk weather. but because under the chassis there are areas of rust. I want to prevent the rust from ruining the vehicle. I understand that I have to clean up the areas before just spraying them. Has anyone done this or have a different answer for fixing a rust problem. I wish I had pics but don't right now. when car comes back from shop I'll definately take pics of car.

Just follow the instructions on the can of which ever product you wish to use, remove mil scale/surface rust, treat with your preferred rust inhibitive product, then finish/undercoat/whatever.

before and after pics plz.

thats exactly what i did... i bought some of that primer that turns rust into primer as you spray over it, then i undercoated it with rubberized undercoated i had at my shop... oh, and it looks really good in your wheel wells too, cleans everything up

do you recall the name of the product you used that turns the rust into primer. I was looking at Rust-o-lium that my father has in his gaarage.

buy an angle grinder. A wire wheel for it. A face sheild. Breathing mask. Thick pair of gloves.

Follow instructions.

yep POR15 is the ****



i have some



it even comes in different colors!

ZeroRust

that **** will still rust no matter what you put on it

You saying that your car has no rust, or you used the product and now have no rust?

Zero rust is a product, not a condition.

Quite a few people, including myself, have switched from POR15 to zero rust.

Its easier to apply, and in my opinion, much harder to remove from properly prepared metal.



I am thinking of doing a test on it. Scuff a piece of sheet metal, and coat zero-rust on half of it. Place the sheet of metal into salt water, and apply DC voltage to the sheet metal and the salt-ion solution. Should form rust VERY rapidly. Leave the systen running for a month or so, and then check back to see if any rust got through the paint.



Any better/simpler tests possible?

Sounds quite impressive, i'll take a look at that link in as soon as i finish this. I'll probly answer my own question when I visit the site, but is this product special order from the site or can i get it at a auto store some where? just so I know.

call me an idiot if you will, but I didn't see where you could find it as in what stores or how to through the web page.

Today the first words from the mouth of the machanic when picking up the car was "get under the car clean up the rust and undercoat." Then he went on and told me about the work he on the car.

Most auto paint suppliers can get it for you... something like $50 per gallon. Also available in spray cans for $6 or so per can.



Call some body shops; they should be able to hook you up.



I buy mine locally through a tool store thats sells Nason (Cheap Dupont) auto paint.

Thanks. I don't think I'll have undercoated the car before the first snow fall, but I'll have the stuff to do it.
