Hi guys.
Got the seats of my HK out, began pulling out crumbling vinyl floor to repair rust. The rear floor section was wet as. The car has been in storage for 8-9 months, at least. I thought it would have dried. The under lay material was wet long enough to the point it was black from rot. There was newspaper stuck to the floor. As I was cleaning it up, there were a number of punched holes in the floor, bit smaller then the size of a 1c coin which I assume were drainage holes. Thing is there was black adhesive/sealant blocking most of them up.
Question time. I assume their drainage holes? What are the upside down ashtray looking plugs screwed in? I spoke to someone and they weren't sure. They thought the black stuff was from when the floor was put in. Thing is this black stuff covers most of the holes. I thought they would have been careful enough to not allow flooring adhesive to fill drainage holes.
Thoughts on which way to go forward.
Thanks, Jeff

Sure it was newspaper? Not a build sheet by any chance?

The Dandenong bodies were the same. I've even found little sheetmetal offcuts embedded in the sealer in the 3/8" holes, in fact so often I think it was deliberate. Watch out for that Elastite sealer - it's full of asbestos.

The small holes were drains for use during the manufacturing process, as Byron said. The larger holes covered by a "top hat" plug fixed with self tapping screws, so they could be easily removed to drain the floor should you attempt to ford a river, or drive the car into a lake.
These days the entire car would be written off by the insurance companies if it got wet above the sills.

Byron, what do you mean by "bodies in white"?

Cool, thanks for the replies.
So HK1837 with the holes, leave them as is or fill them in? I don't want to have a wet floor issue in the future like I've just come across. It looked nasty and would have rusted the hell out of the floor. Fill with adhesive or MIG?
gm5735, yeah newspaper. when it was stuck to the floor I could read the writing. It had vinyl, heshen type material underneath this and then newspaper. But it was black with rot in most places and the drivers side had a rust hole I could put my fist through. Thanks about the black elastite. I have been chipping off with a screwdriver/scrapper as I've been warned about it. Don't sand it asbestos material. Regardless, I wear a good dust mask when I sand.

thanks
