If these were turmeric stains, they usually fade away with regular washes. For residual stains, claying and compounding will do the trick.

But bird poo is very very detrimental to the paint, they need to be cleaned as soon as possible with ONR/PBW Bird sh#t remover.

If etched into the paint, needs paint correction as well.

Thank you. I am pretty sure it is has gone deep till or into clear coat too. Washed car just the day before and was not happy seeing this. Since I live in coastal area, I have coated car with multiple layers of wax and sealants. Checked yesterday night with a LED flash light and could see it being embedded below surface.

As you said, I hope it fades with light. If not, have to take the tough way out with pain correction.

Check with the 3M guys once (someone competent), they removed such deep stains once from a friend's white car

Guys, need some help to understand the usage of sanitizers over car's body (painted surface) and interior. The first service of my Nexon is due and I had a detailed conversation with the SA regarding the precautions they are taking at their service center. He informed that they are sanitizing all vehicles as soon as it arrives for service and the procedure is repeated while handing over the vehicle.

My question is, does it affect the paint in any way or plastic panels? The SA claims that the sanitizer has been approved by Tata for usage on automotive surfaces but I have my own set of doubts on its usage stupid:

Hi Sumit,
I have just visited a Tata service centre in Goa for a minor fault. The car was sprayed with this sanitizer and initially it did leave some whitish marks. However, after it's usual wash by the car cleaner the next day, it was back to normal.
Hope this helps.
Cheers,
SS

I am not a professional detailer however I do have a ceramic coat on my vehicle so answering from my experience. If the water beading and sheeting has degraded drastically then either the ceramic coat is gone or the ceramic coat is covered with contaminants badly. I am inclined towards a degraded coat. Now waxing/polishing can be done but it would hardly stay because the paint itself is not clean so it would be a weekly job with waxes or polishes. More of a hassle if you ask me. Rather get your paint decontaminated and then continue using waxes or polishes as usual.

Sanitizers usually contain IPA diluted to min 60% to max 90%. IPA would remove any wax coating (if done) from the clear coat.

Hi Folks,
Being a DIY detailer I have been following this thread for quite some time.Now since I am a member I finallIy get a chance to interact and ask my queries which have been haunting me ever since we bought Artyom home last year.

So the vehicle is coated and the coating is holding good.No complaints there.The pain point is the minor swirls and marring which happens as part of the maintainence.I have been looking for a product/polish which I can use maybe once a year to remove these minor swirls WITHOUT damaging the coating.I say that because the swirls are minor in nature but all over the vehicle.They are visible but with little effort.I have tried to search such a product everywhere and the closest I came to such a product is Carpro Essence+. Apparently this product removes minor swirls without damaging the coating and also imparts a layer of SI02 as well.It can be used with hand as well.

So I have 3 questions for fellow Bhpians:-
1.Has anyone used this product and if yes what are your reviews.
2.Is there an alternate product which can be used every 1 year to remove swirls without damaging the coating .
3.Since you now understand my requirement any other suggestions/procedures you can share to accomplish the same goal.

I guess these coatings have met their match with Sand, same thing they are made of as per their claim.

1. You can sort of fill in the swirls and scratches with a spray on wax, it gives some relief.
2. Polish and reapply the coating which is the proper way of doing it.

- Spray on Waxes won't stay long and moreover using them to mask swirls is a temporary solution.

- Polishing and reapplying the coating is always the last resort and I am trying to avoid it because as a DIY project its too much work especially when you don't have a DA polisher. Instead by spending some amount I can get the same thing done from the guy who did the coating for me for almost fraction of the price.

- I am trying to find a way in between where I can do the polishing by hand just to cover up the swirls for as long as possible after which I will get the whole ceramic treatment done again. Hence this query.

- Moreover polishing the paint, again and again, is also not recommended.

Just sharing my experience and do not consider as paid promotion :).

I had same issue after a visit to my Maruti dealer. Automated washing marred the paint which was kept pristine until then. Was thinking what to do and I am not a big fan of Ceramic coating either.

Then got Collinite All-in-One (325) a.k.a Cleaner Wax. Since mine is a Dzire, Granite Grey paint, it took about 3-4 hours to go section by section. But swirl marks faded significantly. Then was told that it is not permanent and had two choice.

1. Do one round of sealant immediately.
2. Hard wax

Since I had given away my Menzerna sealant just a week before, I had no choice but to resort to old hard wax. Took another 4 hours, but in the end, it was satisfying (as a DIY guy). Though you may or may not have these in your kit, you can try this route if time permits.

End Result in Collinite thread.

Appreciate your response.

Menzerna sealant you are talking about can you share the exact name of the product as I believe there are a lot of them in their range. As in they have their specific name and numbers so if you can share that it will help.

Secondly, the Collinite AIO will that by any chance strip the coating as in does it have abrasives or its just fillers which will mask the swirls.

Also how did you apply Collinite? Sponge applicators or something else

Power Lock

325 mildest that I have used till date. Loaded with Carnauba already, so pretty safe on wide variety of surfaces. It strips (thinnest) and then coats richly.

Status of Sponge after using Collinite 476s

845 and 325 are sponge friendly. But hard waxes will take their toll on both man and sponge. Let this not put you off. Worth it.

You could try something like Megs NXT 2.0. it has some defect filling properties. Similar products to that would work along with a light polish applied by hand such as Ultimate Polish. Maybe even Autoglyms Super resin polish which is a light polish + Sealant all in one

I already have Megs ultimate polish but I just fear that its abrasive in nature and can penetrate the coat.But I can try your suggestion of using a light polish to remove the swirls and see how it works.However I am still trying to source Essence + but unfortunately its not in stock.Not sure from where else can I procure it.
Any leads would be appreciated though.
