Anyone know a source for the underbody pebble finish spray that Porsche put on our cars? I have a call in to the body shop used by my dealer. And, I have been through the Wurth catalog on line (nothing there except black). But, thought it might be faster to get an answer from our Rennlist group.

This is the light grey pebble-finish coating that covers the underbody panels - the front one in my case. See image.

A previous owner obviously went too far over a parking curb. Also scrapped the lower bumper cover. This is an easy repair except for some plastic welding that is needed on a 1" split. Anyone know a source for plastic welding sticks?

Thanks for your help.

I replicated the look very, very closely with Waxoyl. It's clear with a slight yellowy tint. Works great, too. I have used it while restoring Jags and BMW's and even did the underside of an older 4Runner.

Here is an example of the sprayed undercarriage of the 4Runner. It sprays on very smooth. As you can see, it's almost clear. Everything in the picture is coated. Black still looks black, but the tan painted underbody has taken on a slightly yellow hue.

More coats or a heavier spray pattern can emulate a slightly more pebble texture finish.

Hi

Personally I think Valvoline Tectyl and also Dinitrol are far superior to Waxoyl.

I removed all the afore mentioned rubbery undercoat from under the front of my car and sprayed with Tectyl 190.

There were patches of rust here and there where the underseal had lifted, which is what prompted me to remove the underseal in the first place. By the way it was a hideous job and I nearly lost the will to live at one point. It will be spot repairs in future on the rest of the underside.

The product is 3M 08879.
I know several rennlisters told me that the 3M part code in the US differs, but the exact same material that
porsche used and use today is the part above.
It sprays dark , and lightens when dry.
I even painted over it at some areas for touch-up between old and new undercoat.

Bingo! Thank you.

I could use a little of this myself. I had a few scratches from my 'debris' run over earlier this year. A local body shop touched them up for me but they must have used the wrong product as it has turned into indefinitely sticky areas.

Anybody know what the US part no is? Or a vendor? It shows up as something different in the U.S. - a manifold block

On the UK Ireland page I come up with this

Is this it?

I did find this on the US page which looks similar but not the same.

I searched high and low for this product in North America, if anyone finds it or ships a case over I'm in for a can.

Also is this the same stuff they used in the wheel arch areas as I think that is beige in colour?

Sure looks like it. I may look for it while I'm in Europe.

leeshephard

let me know if you get stuck - I can always ship some to you.

Duhh! I was too busy sightseeing. Never got near a body shop supply store.

I did buy some stuff here at my local store. But, it's clear. I'd have to paint the panel first. Since it would be difficult for my paint shop to match it because of location under car, I'm in for a group buy if one of our European brethren is willing to do so.

if someone in the usa gets some, let me know I am down for a can. will also update the post if I find some.
