Hello Guys,

I painted my car around may last year and only a month after painted the paint started to look very nasty! after taking it back to the paint shop, they said that this happen sometimes with black paints and that the clear used gets sucked up and blah blah blah, for me this was all bs...

They polished it and the issue was gone but appeared once again, after 3 tries and a lot of polish marks on the car, I couldnt go on with the back and forward since I am mostly out of the country, now I am back and the paint is still looking awful. I am going back to the shop and talk directly with the owner, im pushing to have the car completely repainted

Does anyone knows what causes this?

Check how the paint is looking:

This is the hood:

 

I see lots of orange peel= bad/lazy painter. The car needs to be properly wet sanded.

 

The painter did not know what he was doing. You'll probably have to sue them to get your money back and then have it repainted at a reputable shop that know how to apply paint.

 

The paint and the clear that they used are either incompatible, or like the above... Lazy/bad painter...

They might have also used too much thinner, bad spray gun setup, apply too much paint and not correcting it before applying clear, or they weren't shooting the paint correctly.

I'd bet it was too much thinner though, as over time it just caused orange peel rather than right away.

If they're not able to fix it, next step is to either have them repaint it, or get your refund and go elsewhere.

FWIW: You are NOT supposed to have swirl marks from polishers. Their incompetent techs used a dirty pad to polish the finish on your vehicle, resulting in caused scratches/swirl marks onto your car. Did they even clean your car's hood before they started to polish the finish? That's a #1 rule when you're fixing the finish of a vehicle...

 

This is a common problem! It is shrink back and that happens when sun hits the paint causing it to shrink.

What they should have done was wet sand and polish, just regular polishing will only mask the look. They need to sand the orange peel flat with 1500 and finer grit and polish it. Another option is to sand just the clear and lay down a flow coat clear on top.

I have had the same thing with my black GS I had a shop respray my hood and they used ppg waterbourne, and I have the same issue. I think it has to do more with the waterbourne paints and hot climates. Water based paints were recently switched up from solvent based for eco reasons.
