I've had a number of them which eventually rusted apart and I've never noticed any glass in them, but by that time you wouldn't expect to, regardless. Will the POR-20 take the heat? It would be nice to come up with a treatment that could be used on OEM mufflers, too. BTW, the OEM damper pipes DO have glass in them. What's your impression on exhaust rust in the midwest: Is it mostly from the inside or the outside? I think the California situation is quite a bit different from ours. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
