No but we'll check it this weekend at the convention. Kieran's car
has a G3 HS header as do I.  His is coated with whatever coating HS
uses.  Which is probably rusting and flaking off by now.  We'll
measure his v. mine that has been Swain coated.

Are cars seem to run pretty hot.  I don't know anything about
who you are using but I have to say the Swain coating is
<RobCadle>Bitchin</RobCadle>.   I recently drove to David Evans
house, a 1.75 hour drive.   I got there and wanted to swap his
cruise parts to my NX.  The car had sat for maybe a 1/2 hour and
the Valve Cover was *HOTTER* then the header was!!!  You could
touch the header longer then you could the Valve Cover!

The stuff works and Swain has donated to the convention 2 years
in a row!  So please support them by using them for their coatings.
