What do you think is the best way to cover up blemishes on anodized alu? I recently purchased this thermal, and it had this small nick on the corner. I was considering using a touch up pen, but wanted to see if anyone had experience or recommendations.

I’ve use the pen to touch up black aluminum it works like magic! Actually anodize of the black I think. Just don’t accidentally let it touch your skin. It burns like acid lol
