Sorry I ment the section of rotor that the pads dont contact(I thought that that was a general known rule) anyway sorry for the confusion.
For calipers I have seen some powders hold up ok. A few paints too.
But the rotors get so hot most coatings i have seen fail after a while.
With the Tech Line caotings I am not sure and have not used yet, and wanted to see if any one who had used their specific products. worked well
Especially those products that are not retail available aka: TLHB, TLTD, TLML
And on top of it all, I was just thinking about the silicon spray as an idea.
wondered if anyone had tryed any thing similer.
Thanks again
Let me know how those parts turn out Johnny
Good luck,
(and remember dont coat the pad contact section)

(or if you do re-machine it)
