How to mask

Hello, I will work with a etch process and all the specs talk about mask the number of series of the piece, but don't say how? What can I use to do that?

Hi, Fer. You haven't given us any details of what metal you are etching, and with what chemicals. There are plugs and caps, tapes, waxes, and other technologies available. But if you explain your situation to a supplier of masking materials like Maskcoat LLC [a finishing.com supporting advertiser], I think they can help you select an appropriate masking technology for your situation. Good luck.

Regards,

Thanks for you advice.

The metal is Inconel and the etch solution will be HF and HNO3. I was reading about wetting agents to improve the etch and the rinse process, this agent really works?
