Iron/rust deposits help

[BaggedG37]

Mike,

My buddy has a 2013 genesis that he just bought, and we noticed when he bought it that it had some orange dots along the back bumper. He's had the car going on 3 months, and washes it weekly, and we've found that they've gotten worse. Recently we did some research and found others having the same problem and that it was iron/rust deposits or rail dust is what it was apparently called. Anyway, yesterday we set forth to do everything we could to get them from the back bumper. We washed the car, pulled it into the shade, then used carpro iron-x remover (pretty much 2/3 of the 550ml bottle). We let it sit as directed, saw it turn purple and reapplied it a few times. Rinsed the car and spent 2 hours clay-baring the bumper to try to get the spots off to no avail. I was wondering if you had any ideas on the next step we could possibly take to fix this issue. Here's how it looks now after our work yesterday, it looks better than when we started, but unfortunately it's still there

Thank you In advance for your help,

Michael Nicastro

Were the spots definitely what the Iron-X was reacting with? Do we know for sure that these spots are ferrous iron particles? Can you feel them on the surface if you try something like "the baggie test" to feel how smooth or rough the paint surface feels?

A. Welcome to the forum B. Props for posting pics of your problem as a newbie to the forum C. If the Iron spray didn't work, I would try clay next

I was going to say the same thing, but the OP said that 2 hours of Claying was tried and the spots remained, that has me a little confused that an iron remover and Claying didn't touch them, if they are indeed iron spots.

Clay (or bug brick) while the iron remover is working. Twice the kung fu punch.

Ewww nasty. Did he COAT or seal them in? Tried an all purpose cleaner or tar/sap remover?

 

[briarpatch]

Try using DoDo Juice Supernatural Ferro Lube.....iron remover/clay lube combo...and maybe a more aggressive clay?

 

[rlmccarty2000]

If the iron-x stops changing colors it is something else besides iron deposits. CarPro used to sell iron-x paste that had a better dwell time. Can you feel it with your bare hands?

I had a new silverado that had them pretty bad and i ended up using stoners tarminator with a microfiber bug sponge and it seemed to do a good job for me it got what the clay didnt. (Sry for the small pics cant figure out how to get them bigger)

You kung fu'd me by ignoring the PM I sent you. Thanks.

Make sure you spray the Iron X on when the car is dry. Also, once you let it dwell for a good 5 minutes or so take a damp microfiber or wash mitt and go over the areas.

Great tip. Thank you David

I saw this reply and it prompted me to check my inbox. Holy cow....over 30 messages in there. For some reason I'm not being alerted to messages? Thanks for letting me know. I also replied to your PM.

Honestly, the iron-x wouldn't necessarily react with those spots itself, it was like the trunk lid, and lower on the bumper it was turning purple. We don't know for sure whether or not it is iron, just based on research and what we've read online thats what we figured it was. Unfortunately at this moment the car is not infront of me so i cannot and we did not do the baggie test, but when i see the car later today i will be sure to test that out. Thank you!

haha, thank you! newbie to this forum, but not forums in general. Forums are a great resource to find information and get help when you're stumped (like we are), and the best way to get a real answer is by showing what the problem is from the get-go, saves everyone time and guessing. We know for a fact its not well water stains, that much we know, and i figured if i didn't post pictures that would be the response we'd get. and trust me, my shoulder and arms tried as much clay as we could bear haha

Honestly, funny thing is is we thought about that. i had older clay that id used, and a new clay bar still in the wrapper so i figured for this job we'd bust out the new clay. we threw the old clay out, and when we had that idea, we were afraid to use the clay on the iron-x and spread it elsewhere on the car or ruining that piece of clay for future use. honestly if that'll do it though, i'll do it and just go buy another piece of clay for future uses. Thank you!

Ewww nasty. Did he COAT or seal them in? Tried an all purpose cleaner or tar/sap remover?

My buddy hasn't done anything to the car to coat or seal them in. like i said, he bought the car with it on the bumper, we figured eh, we'll get them out. bit off more than we thought in this project i guess. Have not tried an all-purpose cleaner or tar/sap remover but if you think that might do it, i mean we're up to try anything. Thank you!

funny thing is, i've heard of the dodo juice before, might have to scoop up a bottle of it and try it, and really just do all of that like you said in one go. what would be an example of a more aggressive clay? For example, i have the Meguiars clay bar, with their quick detailing spray. i used a brand new clay bar for this project too, thinking we'd cover all our bases and hopefully ensure we'd get it out. If you can tell me of a more aggressive clay, i'd be happy to go find it and buy it and give it a try. Thank you!

It would change the purple color, but it wouldnt be exactly where those spots were, it'd be on like the trunk lid, or lower on the bumper from the runoff is where we'd see the purple form. some of the spots we did, we made those lessen for sure from the clay-bar. Thank you!

Hmm, worth a shot, definitely came out good on your truck. i'll take a look into that stuff for sure, thank you!

oh yea. We washed the car, backed it into the garage. it was bone dry and cold to the touch before we put the iron-x on the car. we waited 5-6 minutes before rinsing the car to get it off, made sure it was bone dry before we reapplied, then repeated again before we started clay-barring. Thank you!!

Do you have, or can you get, any polish? It sure seems like you've done a fairly good job at iron/contaminant removal between the Iron X and clay, just wondering if a little test spot by hand of some polish improves anything.

 

[raulddan]

Really strange.
That doesn't look like rust spots to me, and its strange that only the part up of the panel is like that.
Take a look at the roof and hood as I'm curious if there are spots there too.

 

[AutowerxDetailing]

Seems more like paint over spray. You would instantly be able to tell if the Iron X was reacting with those spots if they were iron particles. I would next try a more aggressive clay to sheer off the bonded contaminates.

what kind of polish do you mean? we waxed the whole car with a buffer and Turtle Wax Ice if thats what you mean.

nothing on the hood or the roof. just that back bumper area. whats what is getting us stumped too, because we were reading that (or what we think it is) is iron deposits called rail dust from transporting the cars. that and could be from the brake pads from his brembos. what gets me is like i said that its only forming on that one area of the car.

If its nothing on the roof and hood, they can be some sort of contamination ( brake oil, road contamination or even from exauhst) that its brought in the back of the car and because of the aero and the tailwind that its forming around the bumper to get there. This is my guess.
What its strange is if it where tailwind, the contamination would be on the trunk aswell.
