Didn't work on aluminum Got the marking spray but it didn't work on aluminum with my 10 watt diode laser. The mark wiped off. I tried different speeds and power and even scuffing the surface.

Good service. Good product. The courier delayed my international order and though it was ordered via Amazon (they were not helpful at all) Brilliance team replied to us instantly and patiently worked with us and replied promptly to get the product delivered. So great for service. I haven't don't very extensive trial yet. But was happ to see it helped a nice dark marking on 10w diode laser. Without Brilliance it was only 50% as dark. Waiting to try on other metals.

Expensive! (But amazing!) The laser ink black spray is expensive! But it produces absolutely amazing results on aluminium! We run a 30W fibre laser and have only been able to get polished or light to slightly darker greys with it on aluminium items. This spray is amazing and produces a ranges of colours from black, blues, purples to brown and golds. Well worth the $ if you’re needing to do some fancy marking on Al items.

Unable to make a perminate mark Unable to make a perminate mark. I am sure it is operator error and I will continue trying. Thanks, Gene
