Factory undercoating?

Canadian Poncho · A Poncho Legend!

Are you talking about Body Schutz? 3M makes it. Musclecar writer Jerry Heasley recently purhased a 67 Shelby and one of the top restorers in the country is rebuilding it. He's documenting the process and in this video he shows how he applies the Schutz. I'm pretty sure GM used the same material when they undercoated cars. The first few minutes of the video covers this.

Yes, that's the idea but even that isn't as thick and ugly as the factory stuff!

We had a Schutz gun at work. I might check if they still have it. I don't think they ever use it any more. In the 80's we did a lot of that kind of stuff on new vehicles.

Thick and ugly? That is the discretion of the person applying it.
Do your worst, Carl. Spray 40 lbs of the stuff if you want to do it like Mercedes did it.
If you make it too tidy, everyone will know it's not "factory".

Exactly. I just need to find the right type of stuff.

The GM spray undercoating 10952414 is great stuff but it's rubberized and it's nothing like the original in appearance when it's applied. I sold tons of it at work over the years, customers liked it, used some of it on my own cars but as far as it looking original it's a fail.

From what I understand the 3m stuff is pretty spot on. Application is the key to how thick it is. The other option is going on Yenko.net and asking the guys who restored their pricless LS6's etc what they used.

I'm with you on this carl. I've tried lots of schutz methods. But it all flattens out once dry. That old stuff is like the walls of a cave

My body guy uses a thick bed liner application.

Some people want the wells body colour.

He can put any colour into his mix.

The colour is in the mix so it won't chip off.

He says it cleans up really good.

That actually would work well in many of these 60's Canadian GMs.

No, I'll have to look for it.
