Front bumper discolouration on my 4-month-old Tata Altroz

Not able to pinpoint the exact cause of the decolouration.

BHPian dijkstra recently shared this with other enthusiasts.

Hey guys,

I have a 4-month-old Altroz in red. Recently noticed that a portion of the front bumper just below the grille is devoid of the normal glossy finish. This is only after I took my car out for a spin on a rainy day - do not remember noticing it before. I have no idea what could have caused it. But it looks like a corrosive substance (or maybe heat?) took away the clear coat.

I only recently sent it to a TASS body shop for a scratch repair job on one of the front doors. Not sure if it could be something of their doing, but won't be surprised if it is (the body shop guys managed to add a scratch on the same door panel they repainted).

Would be very helpful if anybody can share their thoughts on how this could have happened and what I can do to fix it.

Here's what BHPian AJ56 had to say on the matter:

Having seen how they work at dealerships, including the high-end Germans, I can be almost certain they scratched/scuffed that section of your bumper and then tried to buff it out with either sandpaper or heavy cut compound and didn’t finish properly, that’s the haze you’re seeing. The second possibility is they left sanding scratches from the factory itself (Tata paint quality is atrocious, to say the least). Your clearcoat is still left, otherwise, you’d see grey primer.

To fix simply buff with a light cut compound that has decent finishing ability like Meguiar’s Ultimate Compound, Carpro Clearcut, Menzerna 400, etc. and once you see an improvement, use a fine polish to remove compound haze and then protect with a wax/sealant. Alternately you could take it to a detailer to have this done for you (make sure they offer spot correction on phone first as some don’t). Cheers.

Here's what BHPian SS-Traveller had to say on the matter:

Looks like a repaint job, not a factory paint. The shade does not match (it could be a photograph artefact though).

Here's what BHPian shancz had to say on the matter:

Is your front number blade damaged/scratched? That could explain a front nudge that caused a scratch which was covered up poorly.

Or maybe they dropped/sprayed something they shouldn't have and tried to cover up.

My older car had a partially discoloured headlight because the FNG accidentally sprayed something on it and then tried to remove it by using hard thinners damaging the plastic lens.
