High Temp Coatings....   My experience...

I recently bought headers and wanted them coated.  Not trusting my own
application skills (using the stuff you can get from Summit in a can),  I
had them shipped directly to Micro Coat in Santa Rosa, CA.     I figures the
stuff had to be applied evenly at a couple of mils  thickness to stick an
last, and Micro Coat offered "a patented flow coating process",  so I had
him do it for slightly under $200.

The parts ARE fully coated, but they are definitely not EVENLY coated. The
ID of the colectorhas runs and bloches in the greenish grey coating, but the
outside black coating is smooth and even.    Will it last? I have them
installed, and it's easy for me to disassemble the collector to inspect, so
I'll know in a couple of months.


Lessons learned here:

1) Coatings DO work.    I have only 750 miles on the headers, but enough to
know that they do SEEM to run cooler on the OD.

2) Apply it yourself (if you have access to an oven).    The coater,
although reasonably priced (Jet Hot wanted $395 for their coating) did about
as good a job as I could have done.


Just my $.02  worth of observations.  hope this helps...
