Hey Guys,

Long time lurker and now need some help.

I was detailing the frunk and decided to pull back some of the carpeting to vacuum. I came across these welds which look messy but hey this is my first Porsche so what do I know. Are they stock? Can anybody else post some pics of their bare frunk for comparison.

Thanks in advance.

That's not a weld. It's sealent applied to the weld areas. It's normal.

 

Thanks man! I was getting nervous but seriously thanks for the quick reply.

 

Confirmed that it is sealant applied before the car is painted. On YouTube there are some videos of factory assembly of 997s and 991s. You can see this being applied by robots in one of the steps of one of the videos... sorry, I forget which one.

 

I have exactly the same on mine.

I opened one of the little hatches in the frunk to see what was lurking behind all the plastic, and to my horror it looked like a poorly done repair job.

The Porsche sales man (or rather woman in this case) told me it was nothing to worry about as this was a production thing.

 

Interesting.
looks weird.

 

If you can't normally see it, no reason to make it pretty......that would cost more money and time on the assembly line.

 

This is often called body-schutz. Manufacturers use it for seam-sealing, covering welds and to reduce NVH. They can brush it on or spray it. In fact, in your pictures, you can see both--the top part is brushed and the bottom, stippled application was sprayed on.

When the factory joins long seams between panels with welds, they rarely weld the entire length of the seam. They will stich or (more often) spot weld at intervals along the seam. Then, they will seal the seam with schutz to keep out dirt and moisture that could rot the seam.

You will also see it applied on large areas of sheet metal on the interior of the car, like inside door panels and fenders--especially in a trunk. This keeps out noise from outside but also reduces the drumming sound that can be generated as air moves across these large expanses of metal. Driving down the road, doors and fenders that are not reinforced (like a trunk lid or hood) can act like a drum and vibrate at certain frequencies, causing a thrum or rumble as you drive.

Thus ends lesson number one inauto manufacturing.

 

I think this is a macan photo...

 

You should take a welding class...

 

Ha, I can imagine the crap going through your mind like... "did i buy a car that was in a massive front end collision?!"

 

It's like finding out...what really in Spam, Scrapple, or non-descript hot dogs.....best not to know.
