Hi,I have a 40 watt CO2 Epilog Laser Engraver. A customer has asked me to laser engrave red or orange flames onto the outside of 80mm stainless steel tube which is to be used for the exhaust pipe for a car.The customer has provided the graphic and I can engrave it well but am looking for a product similar to CERMARK (cermarc.com) to provide the colour. I have been advised that there are products available but I am having a hard time trying to find them.RegardsCountry:Australia
