Which Type of Bung

[Phil Hayden]

Thinking of doing some chassis protection through the winter on my TR6 and seem to have read about drilling the chassis and injecting wax oil and then inserting rubber bungs.

I'm having difficulty locating the thread but my question is, do the bungs need to be or a certain composition so as not to be effected by the waxoil.

Any guidance appreciated.

Thanks Phil

any grommet will work, depends on size of hole  simple electrical easy to find ,  why not just leave it open  to breathe  a little
