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 product, great staff. Was leary about the product and I am just starting out in the laser engraving field. They sent me 2 samples, red and black. Both work as advertised. Will be purchasing the product for continued use.

Super service and product works great! Changed the product to one that could ship to my APO and still meet my needs. Constant updates on shipping and replacement. The best service I’ve had in some time. Thank you Brilliance. The product works great. Still tweaking it's use though. BTW I use a 40W Diode and it burns great at speed of 9000mm/m and 60% power on thick aluminum business cards. Thank you again.

DO NOT WORK WITH COMPANY !!!!! The product didn't work as described. After requesting a refund and return label i received the runaround. After responding to several emails (10) the company cut off Communications. I have now started a dispute process with PayPal. DO NOT WORK WITH COMPANY !!!!!

Good product for Stainless Steel engraving Give me surprise results with my 10w diode. But some of the coating may be blew out by the spray air during spraying procedure. Take time to learn.
