So, everyone needs to call the major parts houses that sell A-Body parts and ask them to find a supplier for real rubber hounds tooth trunk mats.

Rubber is just nicer than vinyl. If someone still makes them, please let me know.
Thank you
They make them for first gen Camaros, can't imagine why a supplier wouldn't have one for other cars if they were so factory equipped.

Our 69Z with deluxe interior comes factory with a pretty thick rubber trunk mat with a houndstooth design on it. I had to buy a new one, they are just over $100. Not a cheap trunk mat but very nice quality.

They were an available accessory option for basically every model of every year.

Absolutely agree. Condensation is a problem, especially if you have an air condition garage . The cool air in the garage will speed up the issue when pulling your hot (body) car in.
Next time at a car show, lift up someones mat. More times than not, you will see some minor rust starting.

That was more of an issue back East and pretty commonly seen when I lived in Ohio.

Out here in Arizona not so much of a problem when you have dew points in the single digits and 15% humidity. The mats themselves disintegrate from decades
of use while the trunk floor remains pristine.

The over the Pontiac Parts counter Accesssory style I'm acquainted with from the late '60's were of a thick light gray flexible material. I've had a few NOS from dealer buyouts & have a lightly used one.

Like the much thinner assembly line installed rubber mats, I don't like them. Just pulled in too many projects & parts cars from TX, OK, even from out in NM, where the thin rubber style mats were stuck to the trunk floor. Once the thin mat is carefully pulled up, there's a rust stain on the back of the mat, & at the very least minor rust pitting on the trunk floor. My '72 T/A had a thin trunk mat mat as part of DLX trim interior option. Unless I find a perfect used '72 mat & then go to the trouble of installing & removing it, I doubt the '72's trunk floor ever gets a mat again. Even after refinishing with epoxy primer & modern paint, I'm paranoid about condensation & rust.

Same opinion. My rule of thumb when I got paid to think was if average RH is below 50%, risk for corrosion was negligible. Sure, if water sits, it will cause corrosion, but that's a different discussion. Condensation in the desert southwest can happen, but any condensate won't last long before it evaporates, even under a mat.

There is a "technical" thing called capillary condensation that can bite you when two surfaces are in contact, but like Formulajones, if the RH is 10 or 15%, even that scenario is unlikely.
