This is a bit messy. In order to get an even coat, it usually takes enough that it drips off the item. However, it's easy to clean up. It's pretty much just powder once it dries. It works so well. Even works well if the coat isn't perfectly even. Using this on a stainless tumbler has been a game changer.For the record, I use this on my diode laser. Longer Ray5 20W. Looks great every time. I printed a CD cover on a tumbler. The song text was tiny (tiny!). Not able to be read easily with the naked eye. However, I took a picture of it and blew it up on my phone. I was shocked to see it was all legible. Wow.

Had a project I needed to use this for that required engraving a phone number on stainless steel - but did some other testing on more stainless steel items. This sprayed on very smooth and easily. However - word of caution - this product is like spray chalk. It will easily rub off so be careful handling it after it is sprayed on. Took about 5 minutes or so to fully dry and was ready for laser engraving. I set the 40 watt Epilog Mini laser with power at 100% and speed of 10%. The results speak for themselves. It is definitely permanent and shows no signs it will fail. Great product!

Advertised as a 25W co2 laser spray. I have no idea why. It works perfectly with my 12W diode laser.

I sprayed some stainless flat scrap, followed the instructions that are included, and burned a few logos using my 100w C02 laser.Set at 25% power, the prints were tight, crisp and even. Very impressed.To judge wear, I took a large eraser to the markings to try and get it to rub off. Nothing came off at all.Great product to add to my shop.

I have had nothing but issues with this product. It marks the material just as stated there is no issue in that. However, EVERY single can I have ever purchased (5 over maybe 6 months) has stopped spraying material out of the can. I have followed all instructions, kept it in a warm place, even soaked the nozzle in alcohol after every use. No matter what I did I would get maybe 2/3 projects out of the can and that was it. It would not spray out any more product like it ran out of Aerosol. I even contacted Omtech and sent in my patch numbers from the bottom of the cans each and every time and was given the same response. "We had a bad batch and are aware of the issue." Was even sent 2 cans from Omtech and had the same issue over and over. I have given up and will NEVER purchase this again. Go with the Brilliance or XTool makes a spray now, I am going to try those but PLEASE save your money because this product is GARBAGE!

Although its not cheap, this product does exactly what its supposed to do and it takes a very thin layer for it to work so really the cost isn't as bad as it seems. I have laser engraved numerous stainless tumblers and I'm currently on my 150th brass medallion and I still have it seems over 1/2 can left. If you've never used this type of spray before it goes on as a liquid but wipes off like its dust. I can run the product under water and this spray comes off with very little effort which is AWESOME.

Product arrived on time.Worked perfectly on sample metal pieces I was testing.Follow directions and results will be as advertised.

Doesn’t work exactly as promised but on half of my projects it did fairly decent.
