Let me tell you an interesting fact before corolla i had suzuki mehran. I kept that car for good 9 years and during all these 9 years that car was always parked in open under scorching sun without even a single bit of cover. It faced 2-3 hail storms atleast (the ones i remember, there could be more) and apart from only one small dent on roof there never was anything else on that car.
The crux of the story is we all hat suzuki for the shit it produces and its all justified by mate toyota indus is not different ... they all are shits !!! the worst quality cars at highest prices ; this is what we are getting
And believe me my corolla 2017 has worst paint job from indus compared to that mehran that i bought back in 2007.. i can see the bubbles in paint !!!
To your rescue dry denting can resolve your issue but for that you require skilled worker and thats the irony in pakistan !!! we dont get skilled labor ..every tom dick and harry becomes a ustad and opens a workshop claiming he knows everything
Find a good dry denting shop , they have a specific tool for such jobs. these can be removed easily if you get the right person to do this job
