Help! holes in the bottom of the front trunk, not rust related! Options

[bradtho]

I've got my work light underneath on the left so you can see better. There's a matching set on the right side that aren't lit up. They are shaped like a figure 8 (upside down in this view) meaning that it looks like someone put a small hole in, then decided they needed it bigger and offset. all 4 holes have this same size/shape.

First thing, any clue what these were for? Looking underneath, it appears that something was attached underneath, but the cars are so low I can't imagine what was attached.

Second, what would you do to plug them? I'm trying to prepare for the return of the rain (this is a DD). I was planning on just using some conical rubber stoppers, but the oblong shape is going to make that a non-starter. I'm afraid any kind of tape will just hold water and be worse than nothing at all. Is nothing at all my best shot?

It would be a real shame to let rust get started, it's in such great shape now.

Rust doesn't start because there is a hole, it starts on unprotected metal. Clean up around the holes, prime, paint and find some rubber plugs. A round plug in those oval holes will most likely seal better than your front hood gasket anyway.

I agree, don't use rtv silicone. Just paint it to seal it and put a rubber plug in it.

Put a nail in a jar with a glob of rtv and put the lid on it. After a day you won't want to use rtv on your car anymore. If you don't have seam sealer just use regular latex caulking for the short term. It will last for years.
