Long ago I used Sherwin-Williams Polane T paint. I think it was "T". This is not an endorsement. Check with S-W, or your favorite paint supplier.

Any way lots of suppliers make low loss paint. I don't know of any "no loss" paints.

Apply per manufacturer's instructions. You'll need to prime (acid wash)if you are painting over bare metal.

Good Luck.
