| Ask on the detailing forum at benzworld, you may get a quicker response. As for using Teflon (PTFE), it's just a gimic, if it truly worked the large companies like 3M, Turtle Wax, Meguiars, Eagle One would be doing it. For now I stick to using PTFE only on my frying pans and even though they have a good thick coat of it, they are not very shiny. |
