Coating thickness plays a very important part in the quality and darkness of your mark.
Laser Bonding Technology recommends a thin, even and smooth coating. A thicker coating will require more laser power and will also decrease the resulting marking resolution. Less is more!
LaserBond 100 uses nanoparticle technology which allows you to obtain rich black marks with less material. You should not apply it as thickly as you would spray paint or other products.
Austin Engraving Solutions explains the idea perfectly below:
"I often forget this and make sure I cover a yeti completely in a thicker layer of coating but in reality it’s not necessary. You should be able to see the stainless glimmer below it."
