Can this be used on kitchen faucet with a metal primer? If so do les it need a sealer over the top?

Thank You! When That clear on can advises not to use over the Bright Coat Metallic Finish. I purchased the Universal Clear Durable Top Coat High Gloss

Thanks for reaching out! Rust-Oleum Stops Rust Metallic Spray Paint can be applied to a primed kitchen faucet. For added protection we recommend clear coating with Rust-Oleum Stops Rust Clear Spray Paint. We do not recommend using spray paint indoors, the faucet should be removed and painted outdoors or in a well ventilated area like an open garage. https://www.lowes.com/pd/Rust-Oleum-Stops-Rust-Gloss-Crystal-Clear-Spray-Paint-Actual-Net-Contents-12-oz/3544060 - Rust-Oleum Product Support 6
