Caswell's "Tinted Brass" and "Candy Gold "

[autoshopowner]

I have a question for you. I purchased Caswell's "Tinted Brass" and "Candy Gold " in hope of finding a color that was close to Cadmium plating found on disk brake caliper brackets. I have been using electrical outlet covers for color samples to show people. I ran two samples of each of these colors and they came out transparent. They have color but you can see the bare metal right through the powder coat. The pieces were well coated and the surfaces are very glossy. I only did one coat, and will try a second coat. any suggestions?

they are both transparent colors
you will always see the metal below if you don't use a base coat
you'll need to coat with a chrome base first and then top it with gold or brass

to make it look more like cadmuin or zinc palting I would use a silver base instead of chrome

Those colors are transparent/candy colors meaning it's almost a tinted clear so to speak. You could try a basecoat of something like Mirror silver or X- treme chrome and then the transparent/candy as a top coat.

Is there a Caswell power (part number) silver, you would recommend? Sounds like you have done this before. Any hints on the double coating. I have the Red Line Alpha gun. (great gun by the way)

I,m more familiar with a different brand of powder but I looked thru Caswells and I think I would try Silverstone Metallic (p/n PCPPMB847). I don't think you would want a sparkle silver. jtagger 19 may be more familiar with Caswell.

I have some Silverstone Metallic left over from some rims I did for someone. I had forgoten about it. I will give it a try and let you know how it turns out. Thanks. Happy Holidays.

Ok, second attempt. I used the Silverstone first. Set the gun voltage to 75,000 and put just enough powder on to cover the metal. Went through the normal cure cycle. Then I applied the canny gold to two pieces and the brass tint to two pieces. I cranked the voltage to 100,000. The gold barely stuck and did not cover hardly at all. The Brass tint covered better but did not cover well either. I went ahead and cured all the pieces. The gold one you can hardly tell I did a second coat on and the brass covered a little better but not well.?

The pieces all started out as bare metal, the Silverstone was applied to all the pieces equally and all at the same time. What am I missing?

Oh yes, before I did the second coat I took a die grinder to each one in a small area so that I had a good ground.

I aswered your PM but anyway ,to get close to the color
don't use metalic use a solid tone silver
I'm not familiar with caswells silvers so I can't say wich one

if you are still using electrical outlet covers I had a similar problem with them on second coats specialy around the corners , try something else .

I read you PM and it has helped. Still more questions. I sent a PM but here is the text anyway.

So, use 50,000 for all the coats? Coat the gold several times (cure then coat)? Not sure what to try it on, I do not want to go right on the caliper brackets until I got this down. What do you use to create color samples? The instructions on the Silverstone are 400 for 10 minutes. Still do the first coat for 120-150 for 20 minutes? Should I also recoat with gold while still warm or hot? Any help is greatly appreciated. Happy Holidays

Recoating pieces hot or at least warm makes the second coat stick a lot easier. Really I try and coat as hot as much as possible.
