Subject: Baked on finishes

I'm aware of powder coating.  I've been told that its an infra red
heat cure process.  I make soldered sheet metal parts and the melting 
temp of the solder is about 400 degrees. Is there a powder coat 
that will cure at this temperature?
	Also, what is the "baked on" appliance enamel?  Is this the same
thing or a different product? What temp does this stuff cure at?
Thanks for any info you can give me.

I worked for a guitar (steel body) manufacturer that had their guitars
powder coated. If you can go with a slightly high mlting temp you will be
better off. The powder coat wi applied at alittle bit above (as best I can
remember) 425 deg. F. For more info you can call San Luis Powder Coating
and get more details. They have found several colors that just would not
work. The problem is the high temps melt the solder and leave a depresion
in the powder coat that shows up pretty easily...
If you need their phone # email me...

Get in touch with Bruce Corneto at Micro Coat. He deals in ceramic
coatings and has some very nice colors as well. Tell him that I sent
you and he will be happy to expalin his process. It may be a viable
alternative for you other than powder coating.

We have a guy in the Bay Area Engine Modelers that regularly bakes the enamel finish 
on his engines.  He grabs just about any old enamel and paints the engine.  Then, 
after it is dry, he puts it in the oven at around 350 degrees F.  The enamel flattens 
out, becomes very glossy, very hard, and, for the surprise, changes color.

Not blue to red but red to maroon, etc.  That type of color change.  

However, the finish is bullet proof.

Another approach is to use enamel with a catalyst that will cure the paint in 24 hours 
so that battery acid will not touch it.  Very glossy finish.

Warning.  The catalyst is dangerous to breath.  Automotive refinishers use a supplied 
air mask and a full body suit to spray this stuff in a booth.  Course yours truly has 
been known to spray it with just a respirator when outdoors.  Now I consider this 
terminally stupid after understanding the dangers to the lungs.

Best regards,

I just purchased a Wade Profiler model #242.  I need a motor pulley 
assembly and 3/16" Houdall collets (2) or a set if you have such available.
