Rubber Plugs

[captainkim]

Sorry if this has been discussed before but ....I drive a 71 240Z ......What is the purpose of the rubber plugs on the floor , trunk , etc?   Water still seems to get in..   Can I just fiberglass it shut or is there another reason this needs to be accessible?

 

thanks

If memory serves, they were made to drain the excess paint/coating as cars back then were dipped in vats of paint? 

 

I suppose you could, but really water shouldn't be coming up through them unless they are torn or rotten. I would check door seals and the hatch seal and make sure the rain channels aren't blocked.

I wanted to put some fatmax on the car, but if the plugs do wear then i need to cut a hole in the sound deadener for the plugs so i can change them when it rots again.   there are so many plugs also!!

I'd just replace it and cover it. My car was in active service for 30 odd years and the plugs were still alright. 30 years down the line you can cut out a patch from the mat and replace and recover. If you are going to close them, I'd suggest more permanence then fiber glass. Weld a patch and seam seal it. That will also tell you the health of the surrounding metal which if it is constantly wet might be worse off then you realize.
