Bill,

First of all, remember that powder coating is just paint that is applied dry, 
electrostatically, and then baked on versus sprayed on in liquid form.  No 
mystery here.

Roger Moments gold level BN1 has had the majority if not all of its 
suspension podercoated.  Roger even has the Eastwood powdercoating system, sent 
to him 
for evaluation, and does many of the small parts himself.  Additionally my car 
which is being restored to Concours standards will also have most of the 
parts powdercoated.

Roger uses Cardinal Brand black in an 80% gloss and I prefer the same brand 
in a 60% gloss.  Both very close in sheen.  The parts on the Healey were 
originally a gloss black that faded very quickly, so gloss is the way to go.  
The 
one nice thing about Cardinal is that they also sell spray cans in the 
appropriate gloss levels (40%, 60%, 80%) for those small jobs.

The powdercoater that I use, Small Parts Powdercoating in San Marcos, CA has 
a very nice process. After they bead blast the part they run it through a 
phosphate coating machine for rust protection and then apply the powder while 
cold.  Many other vendors apply the powder to an already warm/hot part, with 
the 
results being that the coating tends to be a bit too thick.  Using the Small 
parts method the powdercoating ends up being about 5 to 7 mils thick, the same 
as paint This leaves a lot of the detail in the parts intact.  Outstanding 
results in my opinion.

Hope this helps,

<< The conversation regarding cermaic exhaust coatings has me thinking.   
Anyone 
 try powder coatings rather than paint on suspension parts, rear axle, or  
any 
 other under parts exposed to road debris and dings?  BTW, whats the  finish 
 for those parts, ( painted or powdered); gloss, semigloss, or flat  black?  
How 
 does all of this effect originality?
  
 Thanks for your reply,
