Can anyone explain this? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Over the last month or so I have noticed dimples and dents on my driver side rear fender. They are very subtle but noticeable under the right lighting.

[ame="http://youtu.be/PZ8fuNQ_-5Y"]http://youtu.be/PZ8fuNQ_-5Y[/ame]

The car has zero accidents, there's no paint damage or indication of impact. Purchased new in 2013. The only theory I can come up with is:

-Factory defect that I haven't noticed until now?

-twisting and torque on the chassis from driving hard (I do that a lot) has caused the sheet metal to warp?

-Structural problem with the car is causing sheet metal to warp?

Im not writing this because it really botheres me. More so curious to see if anyone else has seen this

Do you ever park under trees? Specifically oak trees?

Not that I can remember. Are you thinking acorns? The dents aren't consistent with small impacts. It's more like wrippling or warping rather then small dimples.

I watched the video again and see what you mean. Maybe a large branch hit it? I'd have PDR fix it and see if it returns.

I just had another look and noticed the car is sitting a half inch lower on that side. Which makes me wonder if there is any suspension damage. Perhaps a hard bottom out could have caused this. The force through the strut tower could have been absorbed by the sheet metal.

Someone's butt cheek from leaning on the car.
Get a heat gun and try to massage it out from the inside.

Ultramaroon · 10-29-2016, 01:40 PM

Yeah, someone leaned on it. I put a tiny dent in mine above the driver's side rear window just from supporting myself. Leaned over a little too far buffing out some wax.
@swarb - a heat gun on sheet steel? School me. Is this for the paint?

swarb · 10-29-2016, 01:46 PM

@Ultramaroon metal is formed and has some memory to it, the hot/cold expansion would/could help it "remember" its original form. The heat would soften the paint a little a prevent it from cracking/chipping. I would avoid the cold air if possible as hot/cold expansion would promote cracking like glass in the same way. Don't heat it too much and keep the heat gun moving as it could blister the clear coat. You want it hot enough to touch, but not hot enough to burn your hand. Go slow and ramp up the heat.

Holy crap, I see what is happening with the repeated expansion and contraction. That's pretty damn clever!

Guru Woodman · 10-29-2016, 02:29 PM

Or have a guy from a Paintless Dent Repair Company come over and fix it for you.

They are usually not very expensive and it beats ruining your car with a heat gun.

Look !

Hmm thanks for the input guys. I'm more concerned about the car sitting lower on that wheel alone then I am about the dent. But it's nice to know that they might not be related.
