Selective masking to survive Al anodising process
2000
Need to confirm the existence and source for a masking paint to survive aluminium anodising.
Here's the process, proposed for an ALU extrusion
1. Iridite (Chem conversion)
2. Apply masking paint to selected area inside 0.08 in x 0.3 deep slots.
3. Anodise
4. Remove masking paint, leaving a conductive Iridite oxidation protective coating on an otherwise non conductive anodised part.
(peel off mask? , chemical removal?)
looking forward to some confirmation

That's how ya do it! Seriously...that's how I do it, and as long as you have a clean, chromated surface, and a quality maskant, it will work great. Just allow plenty of cure time for your paint.

There are both peelable maskants and ones that do not peel available.
