Suggestions Clear tint paint over brushed aluminum

House of Kolor Kandy concentrate if you want to "roll your own" or get one of their premixed colors. Candy colors are transparent and allow you to build the shade you want. Always best to spray a let down panel before you attack the project.

I've painted outside. Biggest thing is to hang the panel or parts so the painted surface is vertical. As far as local you must have an auto paint store in your area. Something else I thought about is the mid-coat of a tri-coat system. Auto paint store should be able to help.

 

tint clear paint or house of color candy. spray only. i am pretty sure house of color is available in a high quality spray can.

 

How big are they? I agree with spraying a tinted clear (sample first of course). If they're small finding a rattle can with the right look would be great. Bigger will require spraying. You can set up a temp "booth".

 

Matthews Polyurethane color can be mixed with any of their clears to achieve this. Matthews even has a primer/adhesion promoter that is clear, designed to not obscure whatever pattern is in the metal. Testing is necessary to get exactly what you want, of course.

It might be tricky to accomplish this using a packaged product from a local paint store.

"Candy" colors might work, as has been mentioned.

 

do you have any silk screen companies in your area. they might be able to help you out

 

yes ask the silk screener about it. we have never tinted brushed metal but we have tinted materials and they maybe able to help you.
if you screen it you will get a good finish

 

I would try a place like this. They have helped me out with custom color rattle can paints. They may be able to a transparent paint. https://www.myperfectcolor.com/About-us/5.htm
