DetailingGeneral discussion forum for detailing your vehicle.
This is a discussion thread titled "Can Rust be Over the Paint?", within the Detailing forum, part of the Technical & Vehicle Assistance Forums category.
I know this is a Toyota site, (I have an 05 Tacoma) but I have a question about my wife's 02 Chrysler Van.
On most of the Van, (which is silver), it looks like it's getting rust on top of the paint! I've never seen this and it won't rub off even when I wash it.
I always thought rust could only exist on bare-metal....not over paint!
Has anyone heard of this? And how do I get it off? (There's no rust at all anywhere on her van, which spends every night inside the garage...but she does work at the Air Force Academy and I'm pretty sure they salt the heck out of the roads in the winter.)
There is a TSB from Toyota that recomends a certain cleaner (with acid in it) to remove the rust spots caused by rail dust etc. I posted the name somewhere here.
Since it sounds like rail dust BUT you already have the rust forming, I'd do the clay bar first since it's excellent at removing embedded rail dust and other particles and then follow it by the Auto Magic Cleaner as per the Toyota TSB. This way you know the junk is out. Follow up with a nice coat of Klasse AIO (or Zaino if you want to go all the way).
its either rail dust (metal shavings that come off the trains wheels and rails and brakes) or its probably just brake dust thats semi metalic and shows up as specs of orange rust -
Is it like little specks? If so, I think they call it rail dust. Try some clay bar then wax. ----Buzz
Absolutely! Industrial Fall Out, as it's also known as, is present in the majority of cars. It's always a good idea to clay your car when you first get it. If not, you may wind up with the "little specks" you see. It's most common on white and lighter color cars that you will see the spots. Another alternative to claying is a decontamination wash. Finish Kare 1 (one of the Meguiar's brothers) has a nice little set up. You can see it HERE.
I've found surface rust on my vehicles and used Meguiars cleaner wax to take it off. I just thought it was from contaminants in road/air.
You can remove the visible part (the surface rust) with any polish, but it will come back unless you remove what's embedded in the surface causing the rust in the first place. That's where clay and decontamination washes come into play.
You are correct about contaminants in the air "causing" (more like expediting the process) the rust. Rail dust and metallic brake dust are the main causes for the little rusty specks you can see and you have to remove them periodically to comletely solve the problem.
keepin mind that it can also be the metal flake in the paint. My dad has a new dodge ram that is also silver. Some of the metal flakes come slightly through the surfaceof the paint and show up as small rust spots. A good cleaning wax gets rid of it.

If the "metal" flake is coming through the surface of the paint, I'd think that would signal problems such as clearcoat failure in the near future. If the clear doesn't cover up the flake, then it's an awful poor job of spraying clearcoat. Have you given the clay a try to see if the rust comes back after a while? I was also under the assumption that a lot of the "metal" flake paint jobs were not actually metal at all, but other materials that would not rust. I'd seriously keep my eye on that, just for preventive measure sake.
Thanks, I'll keep an eye on it over the next few months...I'm off Monday so will spend most of the day clay barring and then waxing it (By hand.....unless I find a good buffer somewhere.)
As many assured me, the claying process is really quick and VERY effective. Surprisingly so. It only adds another 20-30 min to my wash cycle. I suspect you'll be very, VERY happy with it.
