How To Make Your Porsche 356 Door Weather And Sound Proof!

If I had known you did not have a gun, I would have loaned you one. We do all the pinch welds, and a layer around the battery floor and up the walls about 6-8” to keep the acid vapors away from the metal.

Thank you for the offer. It's done now. Do you smear this stuff all over the battery box?

[@ItalianRevolutionar]

Do you mind if I ask why you didn’t add a couple of weep holes at the lowest part of the door?

[@GarageTimeAutoResto]

@ItalianRevolutionar there are five holes on the door bottom already. Just hit the brakes and the water will come out the factory holes. Actually the factory holes are slots that bend around to the vertical flange. This makes them even lower than if I were to drill new holes. I hope that makes sense.

@@GarageTimeAutoResto It does indeed. When I worked at a Porsche dealer in New England in the ‘70s as a service advisor, few 356s had intact door bottoms!

@@GarageTimeAutoResto Tom. You can paint it with a brush for the first couple minutes, we do the corner bead, then paint the floor. Wait 20-30 minutes, then apply put a heavy bead back over the bottom corners and brush up, from the bead edge to the tape line, rear and outside bulkheads about 3-4mm thick. That urethane is pretty resistant to the acid vapor, we spray Raptor bed liner over the Seam Sealer to look original.

Looking great!

Great job! I decided not to drive it in the rain. Therefore, the underpanels are almost as clean as the paint.

Any reason (besides originality) to not add an additional drain hole there?

[@GarageTimeAutoResto]

The drain holes wrap around the corner to the vertical part. It would be tough to add a hole now after it's all painted and I don't think it would be as low or as effective as the factory ones. I don't view this as a problem as long as the car gets driven regularly after a wet day. If I lived in Seattle maybe I'd have a different view.
