-----Are there any ways to "touch up" hard-coat anodize without sending it back to the coater?
Q. Dear specialists,
We are a medium sized tool shop with no coating capabilities except your common machine painting, but there are several times we needed to "touch up" some hard-coat anodized parts. Are there any options out there short of sending the part back to the coaters to get stripped and recoated? Usually it's something simple like a tapped hole or a chamfer that had to be added after coating....... We understand the color may vary a little, but we are looking for something that has similar wear characteristics as hard-coat...... I am pretty sure most people want to grab a sharpie and color the spot in, but that doesn't work well on working surfaces....... Any suggestions ?
Thank you

A. You should consider brush (selective) anodizing. You either would have to send it out to a shop specialized in brush anodizing or buy the equipment, chemicals, accessories and take the course to do it yourself in house.
An important additional -advantage would be that no other areas but the repaired ones will be affected. Strip and recoat always reduces dimensions overall because anodizing eats about 50% of the thickness of the anodized layer from the base material. Every time you strip you loose at least 50% of the thickness.
