    I returned from a 3 month deployment to South Korea. One of the first things I did after my return was wash my car and swap on the hard top.

    I washed it, then wiped it down with an “in between waxing” product from Griot’s garage I use, then dried it. Everything looked fine in the paint. I am sure I would have noticed anything funny.

    Later, I saw a cleaning cloth I had in my pocket had fallen in a puddle by the passenger sidefront wheel, and I picked it up and flicked it (like a whip) away from the car to get some of the dirt/leaves off it. Some of the liquid spattered back and me, and I suspect, on the car. This is all I can think might have caused the paint defects I noticed a few minutes later. Something has caused the paint to bubble up in a very focal area on that right front fender area. I have no idea how or what. I can’t rule out completely that these weren’t there when I was washing—maybe the light reflection wasn’t right for me to see them—but since I always look at the paint carefully when washing, I am doubtful. There are even a couple tiny ones of these raised areas that appear to be under the edge of the protective plastic wrap where it starts on the fender near the headlight.

    Any ideas what might have caused this? The only stuff in the puddle chemically would have been rinse water from the wash and would include the non-acid stuff I used to clean the tires. That stuff is safe for factory painted wheels. I am sure it has splattered on the car before when I have sprayed it to wash the tires though, and I have never seen an issue, although perhaps the fenders have the plastic protectant down there.

    Any thoughts on what could cause this or a fix short of having entire fender repainted (I am thinking this is only option) would be appreciated!

    Have a great day.

    My best guess is that a truck you were following or possibly something on the road ended up releasinsing a spray/liquid emission of some type onto the Roadster. Then after time it penetrated the paint protection/clearcoat, the paint, to then sit on the CF which then (as it now soaked the paint) dissolved & broke down the paint. If its just on your fender, be happy & fortunate. I always look at how things could of been worse. Inspect the cabin area. The fender can be pulled off, painted and cured in an oven to match the Roadster. The cabin is another beast.

    Sorry to see the pics and hear about this misfortune.

    One things for certain, these things are out of our hands. I curb-rashed my right rear tire and had a scrape on the front right nose of my car hence my current alignment blues. Yes, it hurt me inside emotionally and felt like I had dropped things in terms of taking care of my Roadster, but accidents happen. Its just the way things are. Its only when the carbon fiber is cracked where you should really be concerned. Any issue in just cosmetics / paint, its just that, paint. It can be redone. But we still have our beautiful car. And with the help from the forum we can make sure everyone is covered / taken care of in terms of knowledge and how to carry on and remedy the situation. Again we have a great bunch of people here in the Roadster family.

    True, it is only cosmetic—and I already managed to scrape it up once when I turned too tightly and apparently rubbed against a plastic pole in a parking garage—but you know how it is, even when a defect is minor, when you know about it, it seems HUGE! I doubt it is worth the cost of repainting. I am sure if I let a few days/weeks go by, it will bother me less. Well, maybe a few years!

    That reminds me of gel coat blistering that you often see on fiberglass boats. I can't imagine why it would happen to a car unless your car was wet all the time and didn't get a chance to dry out.

    Griot's Garage appears to have very high reviews from the searches I did. Only thing I found that matched your bubble defect was this below. It matches your theory about the paint possibly having a defect earlier on, and possibly the Griot's Garage application was the perfect storm to unlock it:

    I've actually experienced this after application of a carnauba on a week old repaint. The thinner used if left uncured under the finish will find a way to seep out eventually creating bubbles. although the bubbles started appearing months after. But there was no way it was because of the prep work or during the actual painting. We couldn't tie it to anything but the wax applied.

    I think paint sealants will also lock in the gas the same way as the nuba did. But this is just based on my experience. I'm not a scientist nor a chemist by profession..lol

    That implies that the defect was there in his paint job 4-7 years ago but a wash and wax brought it out now? I don't see how that's possible. I understand it's possible with a new paint job. But one this old? Very strange.

    It's hard to tell from the pics - but when you closely is it the color coat that's bubbling up, or the clear coat?

    Are you sure it is a paint bubble and not just something on the paint? If you can gently push down on it and it gives a little, it is the paint. If it is solid then something is on it. Looking at the sharp edge abound the base of the bubble, it looks like something is just on it. Try a bug and tar remover, it could just be sap from a tree.

    I hope you're right, that would be fantastic news to ViperDoc! Just some clear goo on the surface.

    I use this particular Griot's product pretty regularly for a couple of years, and it has never caused a problem. What is throwing me is that between the washing, and the squeegee and the application of the Griots and the drying it off, I am pretty sure I would have seen the defects. That is why all I can think of is that something was in the water I flicked out of the cloth, but perhaps I did somehow miss it earlier during my cleaning—maybe the sun wasn't right or something.

    It doesn't seem to give when you push down on it. I don't see a sharp edge at the base, but I will try your suggestion and hope it is something like that which dripped on the car. I will let you know!

    Thanks for the idea.

    The previous owner of my car had the same issue right before I bought it from him.

    Tesla took the responsibility and had the paint fixed on guarantee/goodwill.
