Shout to Rust-Oleum's Spray Paints...

Just wanted to share what we use at work...

I work part-time at a HVAC outfit and we prime and paint our exterior vents with Rustoleum's Self Etching Primer and top it with the High Performance Enamel. We are doing the system for a pool room so have to make sure to protect all metal from the chlorine in the vents by using aluminum ducting and painting any metal or galvanized ducting with this.

Thanks Rust-Oleum !!
