Need hydrophobic coating for glass

I need to coat glass with a 20 micron hydrophobic material. What material will be best (nickel, chrome? or possibly anodized aluminum) and how is the process done.

Once exposed to water, metals will oxidize, forming a passive layer of oxides and hydroxides. Also, you are not going to be able to plate glass with metal through conventional means, as glass is not a good electrical conductor.

You should perhaps look into using a fluoropolymer, such as PTFE.

From an engineering aspect, I'm wondering why you are using a glass tube and not simply just a poymer tube. Polymer is going to cost less and better satisfies your hydrophobicity requirements.
