Can I spray a clear over a lightly sanded aluminum frame to seal the aluminum, will it hold up or will it need a base color sprayed first ? Thanks

Yes, you absolutely can spray the clear on by itself to the aluminum surface as you intend to. This will definitely add some protection to the aluminum as well as showcase the workmanship involved with the frame.

when applying the Ink Black PSS-0106 does it first need to be cured before applying the chameleon violet sapphire, or is the Ink Black PSS-0106 sprayed as a base and then chameleon violet sapphire over top then cured?

You would partially cure the Ink Black (PSS-0106) by flowing it out in the oven plus a few minutes, and then pull the part and let it cool completely. At this point you would be ready to apply your Chameleon Violet Sapphire and cure it completely based off the top coat's cure schedule.

Can powder coat be applied to headers and do they have to be bare metal?

Powder Coating will not hold up on headers. Standard sustainable temperatures for powders is around 250 degrees F. Headers get much much hotter than this. I recommend our CERAKOTE line for header application.

I HAVE CHAMELEON VIOLET SAPPHIRE PPB-5730. CAN I ADD A LOGO BEFORE THE CHAMELEON GOES ON? QUESTION 2, DOES THIS POWDER ONLY WORK WITH BLACK, OR INK BLACK?

You can have a logo underneath the Chameleon top coat but it will depend on how you want to create the logo. Of course a vinyl logo will have to be able to handle the curing temps of the powder. Chameleon top coats can be applied over top of any color. We use black because black provides a higher contrast than other colors which really helps the metallic to stand out.
