Hi there, can anyone recommend a spray for laser marking metals? I need a pretty dark mark for aluminum.
CerMark but it’s pretty pricey, I would recommend the spray because I’ve bought the liquid in the bottles and it solidifies pretty quickly if you don’t use it for a while.
Cermark is defiantly the main one at 69 for 12 oz or you can make your own.
Here is a link to a recipe and proof of concept photos.
Will it make black Mark’s on bare aluminum?
Cermark comes in different formulations LMM6018.LF is aluminum and and anodized aluminum
as far as the home recipe I would say make some and try it out. But both are black.
