Please can someone give suggesstions on how to remove rust from underneath my 2006 S430 4MATIC........just purchased it from New Jersey and drove back to New Orleans....H E L P!!!

 

Photos would be helpful so as to ascertain extent of the rust.

 

Buy some evaporust or rust converter on Amazon

 

That really depends upon what your goal is.

Are you looking at just stopping the rust, and don't care what the bottom looks like?

Do you want to make the bottom look new again?

Where would you like to be between these two extremes?

 

I want ALL RUST removed from all the under carriage, control arms, etc. and for RUST not to return ever again. This one I'm gonna keep. My first was a 250- 1969.....

 

Taking the parts off and soakingthem is not my preferred option....One where I can lift the car and remove would be best..............I'm at a lost. Will try and post some pics as soon as I can get back into a shop .......Harold

 

Hmmnn......I would prefer the new bottom look but I guess the cost and process would guide my decision so yes I want it to look new again........ponders that $

 

You're not going to get it to look new again (at least not without sobering several thousands of dollars ) so forget that idea .

If if its just surface rust you are seeing , Spray a rust converter product like por15 or equivalent which will turn the rust into a shiny black protective coating

you don't want to get it to bare /raw metal as that will instantly start to surface rust again

if it's more than surface rust and is bubbling up from the underneath then this is not the car to keep forever , sell it and buy one from California not New Jersey

 

thanks
will try it on my car

 

While it's good to always try rust removal on a test panel before you work on your car, I don't think your cat will like it . It might even poison them!


lol

 

Bad news bud but the real truth is you can't ever stop it from spreading unless you cut it out and replace it with new metal. You can grind/patch/epoxy/prime/paint/sand/buff and it will just bleed through again after it gets rained on 5-10 times. You'll have to do this twice a year just to keep it looking decent.

Some people have resorted to plasti dipping the entire car. There's a thread here somewhere where a guy did it to his 2002 E55 and say's after a year in michigan there's been no bleed through.
