Reducing iron contamination

[quantim0]

I'm having a bit of an issue with iron fallout attacking the pain on my car. It's a '13 Focus hatch and the rear of the car just gets covered with iron fallout every few weeks. I don't live in an industrial area or anywhere near train tracks, the car does sit outside 24/7 though. I took some pictures to show how bad it is, I had just used Iron-X on the back of the car 2 weeks ago. There are other spots around the car that I can see, but they are much more isolated. I can actually see the rust spots in the paint on the rear every few weeks.

How can I prevent this from continuing? I'll go broke using Iron-X at this rate. I was planning on Opti-Coating the car in the near future, will that slow down the rate that iron bonds to the paint?

I find the rear of the vehicles are typically often contaminated due to particulates found in exhaust gases.... that is my best guess anyway.

Could rain also be a factor? Whereas the front of a vehicle gets it blown off more but on the back it has more dwell time?

I think it could also be since you're using Iron-X it leads you to see iron contamination more even though it is a regular amount.

I would try something like Iron-X Soap - use it in your wash bucket. It wont give you that big bleed but, with regular use, it will decrease the build up of iron particulates.

Don't forget that your water (unless conditioned through a DI/RO) may contain, and most likely do contain iron. Because of turbulence the rear of the car does tend to have more "dirt and grime" especially with a wind deflector/spoiler is involved. The air that normally caresses the car as it goes by does find that negative pressure on the back end and settles. Same dead air space I use to improve my MPG when tailgating rops:

Thanx for the idea , will order some on a future order .

I will say the back of the car does get very dirty compared to the rest. Usually from the dirt that builds up on the glass that then gets wiped off every morning with the dew.

I do see the spots, that's how I know it's that bad. Last time I used iron-x I marked it on my calendar and watched to see how long it was before I started seeing rust blooms again during my normal wash. Two weeks was the time.

I will try the soap but it's still an expensive solution at $30/L. Probably cheaper than iron-x and I can tackle the spots that survive the wash with the iron-x paste I have.

Still wondering on opti-coat preventing it.

My experience is with a product my company makes but it is very similar to IX soap. You don't need to use a whole lot of it. There is no point filling up a 4 gallon water bucket, 1 gallon is loads to get over most vehicles. Use at something like 100:1 and you should get away with using about 50ml which is only about $1.5. As above, this is a maintenance decontamination and you wont see bleeding. However it should help.

Opticoat and other LSPs really do very little to help (in my experience) with fallout build up.

I have a Tri-coat white Edge and I believe it is the brake pads that come factory installed that are causing a lot of the spots on the back of my cuv. I am hoping when I switch to ceramic brake pads it will help solve the issue.

Cquartz or CQUK will help more from the irons to penetrate into the clearcoat surface.
OC i dont know,
our coatings once they are fully dry are building a barrier between the open air to the clearcoat.
