Hi @Fishman,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.
I'd suggest you start by giving the mesh a good clean with cleaning vinegar and a scrubbing brush to remove any contaminants that will effect adhesion.
Then apply a coat of Rust-Oleum Canyon Black Satin Paint+Prime Spray Paint, keeping a smooth motion while spraying to ensure an even coat.
If you aren't happy with the results after 1 coat, ensure it is sufficiently dry before applying another.
You might like to check out How To Use Spray Cans for some further guidance.
Let me know what you think and if you have further questions, please don't hesitate to ask.
Jacob
