Angry Paint on hood looks bad...

Iím a bit concerned for the jet black paint on my hood. The car is a 2011.

Iíve used M-Tech quick spray detailer on it about 3-4 times, clayed it, and Carnauba waxed it. Now Iím noticing white, milky marks developing only on the hood, almost looks like burn marks. Iím hoping itís an easy fix or will go away by washing , but at this point Iím a little scaredÖ Has anyone seen something like this? Any recommendations on what to do?

Thanks, you guys are awesome. Phew… I’m actually relieved to hear that. I will start looking into ways to remove them.

Either water spots or etch marks from bird droppings.

It's definitely not bird droppings, that's only happened twice and they were cleaned off immediately.

OP, I like this product to get rid of those marks. also you might have to consider Ironx to decontaminate the paint first

That looks like it works well, but the spots on my car seem worse then the average water spots... I'm going to try a compound.

I would suggest try IronX first then carpro water spot remover, if it doesn't work then compound.

Or go the cheap route and put some white vinegar with water (50/50) in a spray bottle, spritz, let sit a bit, then wipe off. Will need to put wax/sealant back on after.

I don't think vinegar will do the job, these appear to have small cracks and are not your average water spots. I suppose I could at least try it though.

Have you tried a buffer on the hood yet? I'd say give it a try or try a heavy compound by hand. If the heavy compound doesn't appear to take them out by hand give a buffer a try and if that does not work then.......

I've only tried a Carnauba wax by hand, but that didn't help. Let's hope the compound works...

if you can, wet sand with 2000 grit and high speed polish. best to go to someone capable if you have no experience with high speed polisher.

It's been about 2 months since I've posted this, but I went to an auto shop today and they quoted me $200. I tried Megs Ultimate Compound by hand and that didn't help much. In fact, it's continued to get worse.

@sheedi I'm about to order some of that Iron X. Is that clear coat safe? Should I be concerned about putting it on my paint?

like everyone else said , it looks like water marks. I have them too , not a lot but it sure bothers me and they are a pain in the butt to get out.

I take my car to a detailer every 3 months and he gets rid of them because I cant

I sure hope it's water marks, it looks horrible and compound didn't remove it. Also tried Megs water spot remover and clay, no luck.

Wax??? OP, the only time you should use wax to protect the paint, wax cant be used to remove any paint defects.

Thanks! I tried tagging you in a post above. I took it to a shop last week and they would charge be $200 to wetsand it. It's only spreading on the hood...like a disease. I'm about to order the IronX you suggested. Should I be concerned at all with putting it on my paint?

OP, you have to buy both products, IronX and Carpro water spots remover, buy small bottles because you dont need the bigger size bottles.
Follow instructions and apply IronX, rinse and wash the panel.
Follow water spot remover instructions and rinse or wash the panel, hope this will remove these spots, if not then they need to be polished with some abrasive polish.

please read the purpose of both products before buying.

both products are safe to use on paint
