Default Ceramic coat / clay bar question

I coated my car with cquartz uk about a year ago. Car is garage kept and maybe 6000 miles in the last year.

Currently the water still beads great, BUT, I work at a steel mill and some what I believe to be iron particulate debris is flecked throughout the paint which is visible upon close inspection. A wash with a mitt and chemical guys mr pink doesnít get the flecks out. The body also ďfeels roughĒ when gliding a hand over it

So question is how to fix. I did clay small section and it pulls the debris out great. But can I do that or should I strip and redo all process of stripping coating polishing and coating or can I save some time and effort ?

Get some iron x and do a decontamination wash. Using reset shampoo and reload regularly will help. Iron x every few months due to your location.

Iron x products. There are a few options. I haven't tried them all, but I also don't live in an area with lots of iron.

Thanks for that.
I do have the chemical guys iron x type of product to try.

Just to confirm if I do use that product or similar the whole car does not need re coated?

I also have some reload spray but I didnít use it very often still have half a bottle left of it from last years coat applications

Correct, if you use Iron-x you will not have to recoat the vehicle. Finish washing the car as normal and use some of your reload for added protection.

I get a ton of iron on my white paint from snow plows.

A clay bar gets it off but it is tedious.

Never used iron x though.

Depending on the amount of iron you pick up you could get away with the iron-x snow soap. It has a higher cost of usage as you tend to consume half a bottle to mix in a wash bucket or foam gun, but it's a lot less tedious than clay bar or using iron-x panel by panel.

Claying often introduces micromaring in the coating so if at all possible you should be using an iron remover at least once a year, spring and fall are good times, more if you live in an area where you get lots of iron deposits. Only clay if necessary.
If you need to repair a coating you can try a light polish with CarPro Essence Plus. It's meant to fix failing coatings and will fill in spots that are wearing to extend the life of your coating. I have not used this myself, but it gets pretty decent reviews and is probably worth trying if you are considering removing your coating and starting over.

You can't strip a ceramic coating like you can a polymer coating. The ceramic coatings require sand paper to remove. This is why it's important to apply them correctly as any mistakes you make are there for years or require rather major sanding and repainting of panels.

I'm not sure how these ceramic coatings then only last for X number of years. I don't know if they wear away or break off or what as I'm approaching the supposed end of life of the ceramic coating on my car, and I'm not seeing any areas where it looks like a chunk is missing. Admittedly the coating is microns thick and perhaps I can't see it, but I still don't understand how they put a "life" cycle on what is essentially a layer of glass.

You aren't supposed to use sand paper to remove a coating. A compound or polish should work just fine depending on the condition.

Remember: always use the least abrsaive method that will achieve the desired results

The option of using essence plus was to keep the coating and restore it, not remove it.

So I did try a few areas along the bottom plastic running board piece and an area on the door with the chemical guys iron spray with really no result. Didnít see much purple at all and the spots are still there.

So I ordered some actual Iron X which on amazon reviews many state is much better than the chemical guys product.

Will give that a shot. As I said itís still beading pretty good so I donít think it really needs to be compounded and fully redone but I need to find those products to get the result I need. Soon I may try that CarPro soap but itís so expensive to buy all these products at once

I wasn't advocating the use of sand paper. I was pointing out that ceramic coatings are hard. You CAN NOT remove a ceramic coating with polishing compound. If you screw it up you either live with it for whatever number of years it takes for the coating to erode or you pay money for a body shop to sand it down.

Might want to check your facts because even as you stated you aren't advocating using sand paper you mentioned paying someone to use sand paper? You are contradicting yourself here.

You are arguing that a coating is hard like glass and cannot be polished to remove it. If this were true why then:
1. Do companies that make coating say it can be removed by polishing?
2. Professional detailers remove coating by polishing?
3. How then have I been able to remove scratches in windows and windshields using polish and a glass pad by hand and machine? Last time I checked windshields are made of actual, thick glass, yet scratches can be polished out. Hmm...

1.) Companies who make POLYMER coatings say they can be removed by buffing / polishing.

We are talking about CERAMIC coatings here. You do not remove them by buffing. They are harder than a polish / compound and buffer can remove in any efficient manner. Thus the only effective way to remove a ceramic coating is to be aggressive and use sand paper. As most of us aren't auto body / paint experts as a day job it's then generally advised to pay a professional to do the sanding. And this is only IF you for some reason decide the ceramic coating was a bad idea and you want to follow it up with another bad idea (sanding your car).

2.) Yes, see above. Polymer coatings can be removed by polishing.

3.) Check the specs on the glass polish and pads. They are likely very aggressive compared to a paint polish and pad. Also, keep in mind that while we all talk about ceramic coatings as being glass-like they aren't actually glass. They share a chemical compound in silicates, but they are a different material in the end. It is just easier to discuss a clear, hard coating by relating to glass than comparing it to floor tiles which are never transparent and would make people question the clarity of the end product.

I believe in cquartz instructions if you let a high spot dry past the cure time you need to polish/compound to remove the high spot and then re-coat the entire panel. Thus implying a polish/compound is enough to remove the ceramic coating as typically a high spot is coated much thicker than the rest of the vehicle.

I've had first hand experience using cquartz uk the first time. Missed a spot when doing my wipe downs and noticed a very rough spot. Spoke to a rep at the detailing place i bought the supplies from and said i let the product cure and didn't wipe fast enough. He used meguiars compound on a hand pad and after a minute or so of polising the area the spot was nearly gone. Followed up with ultimate polish and it was good as new. Water also didn't bead or sheet from the area so the paint was bare with no coating, sealant, wax protecting the paint.

I've used Mother's clay bar once on the hood because of pain overspray. It's annoying but it helped. If you're going to clay bar, make sure you keep the area lubricated and don't use extra force, as i did and had to do some polishing on the entire car because of some light scratches.

Used iron x today. Had a decent amount of purple start streaking. I let it sit a few minutes then gently wiped with a damp microfiber and rinsed. Then washed again with mr pink. It did seem to help with some of the spots and debris. Maybe I need to do a second time or use more? I did my whole STi and didnít even use half a bottle ...?

I've reapplied ceramic coat after a week of use before, it seemed to work with no negative results. Granted I am using a cheap Amazon ceramic coat ($10).
