Tech-line coatings

[Daniel1312@aol.com]

Hi List,

Does anyone have any experiences, good or bad of using tech line coatings -
either DIY or done professionally.  In particular I am interested in
experiences relating to inlet manifolds (but exhaust manifolds/headers
interests me too).  If you do have experiences can you let me know if they
relate to steel or aluminium manifolds.

As an aside I don't suppose anyone has used them on brake calipers?

Thanks
