Sorry, but I respectfully disagree. If you have water getting into your trunk, you have bigger problems than having a rubber trunk mat.

I was referring to condensation. Constant cycles of heating and cooling will cause moisture to accumulate under the mat. It has nothing to do with leaks....

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.

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.

You really need to listen to Don. He's right about rubber mats causing rust on the trunk floor. The rubber doesn't breathe.



I've seen it first hand. Causes tiny rust pin holes. Whole trunk floor had to be replaced.

I do not doubt that he is correct, but I like the rubber over the vinyl and can keep the trunk floor in rust free condition with the proper coatings. Where I live in Texas is a dry enough climate that we do not have the rust and humidity problems they have in Houston and the Eastern part of the USA.

This happened to me. Moisture got in my tail lights, and started rusting my trunk floor. I caught it in time, and cleaned it up, and re sprayed with spatter paint. I no longer use the mat. I put a blanket on the trunk floor now for my chairs and cleaning tote that I can easily remove or it will absorb moisture and I can simply hang it out to dry and let the trunk air out.
