Hello Dakora 11,
I've been useing a Marking Methods etcher for over 20 years. One thing you should know about all the bottles of electrolytes that came with your unit. Marking Methods tells me their solutions only have a 2 year shelf life. I date each bottle I recive from them. Be sure to look over their list of electroytes, as they offer many types, and each one is designed for very specific metals. They also have a $ 75.00 minimum order
requirement.
Best Regards,
