What to coat interior floor with?

[Will98D]

Finished stripping the old tar mats out of my '74 914. Some surface rust under them where rain/wash water got in, especially under seats and near pedal cluster, but not bad, no heavy pitting. Treated metal and sealed with POR-15, now I want to seal whole floor and add some soundproofing. What have people used successfully? I want something that doesn't end up gummy, and am thinking of brush-on bedliner material with rubber chunks in it (Hercules brand).

Herculiner? Uhhh... Just make sure not to get it anywhere you shouldn't.

great link... I'll definitely avoid that one!

I've never used this liner material before, but hopefully it will serve both the sealing and sound deadening purposes. They list it as one of the uses on the can, so...

Dave:

That was a great thread... I remember when it first came out. Id id not think it was still available. Thanks for bringing it back.

check out www.b-quiet.com liquid sound deadener. It's similar to a bedliner, but a little better for the purpose. You can brush it or roll it, and it always stays a little soft.

Hi - I just finished the job you are about to start. I used a spray on bed liner from the local auto parts store. About $7 a can, took 3 cans. It sealed real well and looks nice and finished. I do not notice any difference in sound dampening. It is a good watertight interior seal though.

for some sound proofing a cheap method is carpet padding. thats what i did.. low $$$ and did the whole interior at once. ive been told that there is a new spray on insolator for cars that will virtually make it sound proof.

...but the problem with carpet padding of any kind is that it absorbs water and hold it in place to do its number on your floor pans...

Thought the point was to avoid that sort of thing.

Good point, I dint think of that. but it works well in my bug, and should be fine in my 914 if i can keep water out of it .. (good luck to me)

Absolutely correct... I recently purchased an Austin Healey... they're known for lots of engine heat toasting the toes. The PO had installed thick carpet padding and it did both block the heat and the sound. But when I lifted the carpet I found the padding like a sponge that had been left adrift in the sea. As a result the floors were redder'n the Red Sea!

Per the outstanding web page at:
http://www.914fan.com/

"Original replacements can be found from 1-800-WURTHUS. The sheets are 22" X 11" and there are 6 to a package for @40.00/pack + Freight. I takes two packages to do the entire floor. "

Good Luck

IN thinking about it, there may be a couple of other good products to use:

*Bituthene 3000/4000 sheet waterproofing. They are self adhering and bond tenaciously. They are inorganic and of course...waterproof. Ice and Watershield or similar products may be good as well. Get them at roofing supply places.

*Dynamat

Try POR-15. I used it on my Jeep and am very impressed. It won't scratch off, drys solid but flexable (is there such a thing) and is very expensive. But you will never ever have to worry about rust again.
