rustproofing

["jeffm" <jmackd1@yahoo.com>]

Hi, 

Was wondering if other people's TR6 has rubber plugs on the door jams? I
have seven of them on both driver's / passengers side. Just right below the
door striker plate is the first on then every 9-10" is another plug. I
remember back in the 70's I think it was Zeibart company that drilled holes
and pumped in rustrproof material into the body panels. I don't know if
these plugs are stock or someone had my car rustproofed. 

 

Thanks,

Jeff
