I'm pretty sure it is still available from Wurth, however my 67 had an all black brittle undercoat on it. I don't think the PVC undercoat started until 1970.

The 67 S that I have (45,000 miles) has undercoating similar if not exactly the same as used on the 356. It is original & unmolested in the trunk, u pristine. I understand the original product contained asbestos and you could purchase it up until the early 90's and believe it was called Body Schutz. The early product did show some particles that were not black and looked like asbestos particles, and could look grey after many years.
The petroleum base product ends up thin no matter what pressure, what temperature. Unsatisfactory in my opinion. And a fire and breathing hazard for sure. The water base dries very hard but is temperature sensitive. It is best used when the product dries quickly with a warm temperature (above 80 degrees F if possible), more texture, more close to original and the only product other than a shop made product that works. You should experiment with pressure, distance and coverage just like paint so you know what you will get when you spray the car. Both give off fumes so you should use with ventilation. And don't get it on any surface you don't want it on. Particularly a painted body. If it dries you have a problem.
If it were me, I would paint the bottom of the car with your choice of rust preventive paint if you have bare metal. Then undercoat. I just received 5 cases so they do ship in winter but the product is freeze sensitive.
As everyone that has restored a later car with the heavy undercoating, that is a horse of a different color. Very difficult to remove, it can be closely duplicated but does take some practice and product/equipment not readily available. Lots of work.

Ed, you're right about the PVC.
The early cars had a layer of Teroson undercoating directly over bare steel. This is why even on unrestored cars there's a layer of rust UNDER the undercoating-- moisture permeates it over the decades and rusts the steel. This is also why the SWB undercoating is easier to remove than the LWB-- it doesn't adhere as well the thin layer of surface rust. Not that it's particularly easy to remove, but it's easier than the LWB.
The OP's car has been sprayed, if my own experience is any guide, with PPG DPLF, an anticorrosion two-part epoxy primer. It seals the car up nicely-- '065 sat in that coating for about two years and there is absolutely no corrosion present, none, nada. The only thing better would be dipping it in e-coat but this is beyond the reach of Series900. (But not beyond his imagination)

Can anyone report on how many bottles it takes to coat the pan, fender wells and engine compartment? I have the Multi-spray gun that uses the screw on bottles. Not sure the size, but available in black and beige color. One thing I don't understand is that some guys have reported loving this stuff while others have said they do not like it. Too thin one said. Confusing reports.

I redid my whole car, that is, trunk, engine bay, underside, fender wells, and interior floor, but I don't remember how many bottles I used. I want to say that a trunk area was about 2-3 bottles, if you can extrapolate from that.

Mark, 12 bottles. It's pretty expensive and it takes many hours to do correctly. To do it right requires the professional gun.

Eight bottles for me...

My 67S [9/66 German delivery] does have grey PVC under original paint in the interior rear and in the rear wheel wells.
Thanks for the count. Interesting that it took 304065 12 bottles vs your 8. That's 50% more product. Did you both do the same areas? Underside, inner fenders, inside car, engine compartment? Did you both shoot the insides of the front fenders? Did you shoot with the front fenders on or off the car?
