Body plug repair to underside
I'd like to repair a hole that a PO put into the underbody. The hole is behind the passenger seat and goes through what I believe is a body plug. There are several layers of material that are covering the the hole. First, a layer of carpeting. Then, a layer of rubber, then some fiber or fabric type of insulation and then some tar like material coating the metal of the body. Then there is a shiny metal disc and beneath that there is a white piece of rubber, I think. The hole is in this rubber and of course there is a nice layer of beige underbody coating on the bottom facing surface.
The hole exists because a PO wanted to run an extra set of electrical wires to the fuel pump and punched through the body to get there. I'm wondering if I should try to get a new plug to fit into the body, but I am concerned that the process of removing the old plug and fitting a new one would disturb a large amount of intact waterproofing and weathersealing that didn't need to be disturbed and could actualy create a bigger problem than the one I'd like to fix. My best guess is to apply some kind of tar or sealer on the inside surface of the car above the rubber plug, and then spray SEM 39793 Heavy Texture Chip Guard undercoating to the tiny area on the undersurface that was pierced. Please let me know what you think. Here are the wires dangling beneath the car in a rubber sheath  The wires here have been removed. The hole is small.  Inside the car looking into the floor. This is not the best angle, but the shiny object is part of a metal disc that covers the plug.

Hard to see exactly where it is, but first ensure there isn't any structural implications by having a hole there.
As for plugging it, I would remove the local undercoat, make sure the hole is round and smooth, paint all the bare metal, and install a rubber blanking grommet/plug. You could reapply the undercoat but it probably isn't necessary. If you do, you have to do it so that you don't trap any moisture inside. |
