Confirming correct schutz on rear bumper of 73

[mobius911]

I'm restoring the rear panel and bumpers and want to get the undercoat correct on the inside of the bumpers. The car is a touring RS. As I stripped the bumpers I could tell there was definitely a coating of schutz, but some had already flaked off so the exact coverage is unknown.

It appeared to be a relatively thin coat, sprayed everywhere as shown below (from another thread on the same subject). The color was the typical beige or white. Is Wurth SKS beige a good choice? I still have a half bottle that is amazingly still in decent shape after 19 years of sitting around. Any other options since as I understand it the Wurth beige is NLA? Also, does it go everywhere in there, or were certain areas like the mounting surfaces masked off? Thanks for the help!

It wasn't sprayed on the mounting surface and it's painted the color of the car so the color you use probably doesn't matter as you'll paint body color over it. I'm not an RS expert but the 72 and 73 cars it was this way. It's a thin coat if you want to call it that compared to the way the other parts of the car were sprayed with a fire hose!

May not be so much a manner of 'where' to apply the schutz . . .

Could be 'when'


Are all the primers/coatings/paints put on before everything is built-up? . . .

. . . or after?

Yes, the timing of events in the factory is an interesting question. On a 73 the car would get body color after the undercoating.

Whether the bumpers were on the car when undercoated is a good question; the bumpers would probably have to come off before final assembly to install the rubber seal that goes between bumper and body. But it wouldn't surprise me if they fitted the bumper temporarily, undercoated and painted, then removed for final trim and rubber, and then reinstalled. Regardless, I'm coating and painting off the car so will just do my best to reproduce the correct finish in the correct places.

Hi, the order is, primer, coat, colour.
The following pics is of 74 MY, but it was the same in previous years.
Consider also that a RS Touring had the same specs of a normal 2.4S of the same MY.
The interior of bumpers, as the interior of the car and luggage compartment, was painted in a very light and quick way.

This has to be qualified by 'it depends.....'. If the RS 472 or 471 was created as an RSH first before the conversion to a 472 or 471 model there would be very little undercoating. Far different than a series production '73 T, E, S, or third series RS.

The bottom of the car also had a very light coating of body color paint which barely covered the primer of an RSH. The series production cars had more paint applied to the primer and undercoating on the bottom.

Thanks everyone. I'm going with a light coating, which appears to be correct and the same as my bumpers (third series RS) were done originally.

Of course.

Well done !
