Have you looked at Rust Bullet ? We'll put it up against POR-15 and or Zero-Rust on any test you wish.

POR15 is more like a hard/slightly flexible ceramic surface. ZeroRust is more like rustoleum . . . i.e. if you smack it with a hammer or brush up against it with something abrasive, it comes off pretty easy, not so with POR15.
An Abrasion Test (ASTM D4060) was performed by National Testing Standards, Inc on POR-15, Wasser® Brand System, and Rust-oleum® Cold Galvanizing Compound.

Method: Original specimens of panels above were evaluated for abrasion resistance in accordance with the procedures set forth in ASTM D-4060 Taber using 1000 gram load and CS-10 abrasive wheels. The Results:

Specimen Cycles to Wear-Through
14,000 Cycles RUST BULLET Automotive No topcoat
30 Cycles RUST-OLEUM Cold Galvanizing Compound
4,000 Cycles Wasser Brand System (Urethane)
10,000 Cycles POR-15® System topcoated with NAPA Ruf-Nek Heavy Duty Spray Paint

As you see Rust Bullet tested far above any of the others.

if you smack it with a hammer
This was similated in the Impact Resistance Test,(ASTM D2794). Again, Rust Bullet won on all accounts.

Results: Wasser® Brand System and POR-15 showed cracking of the respective paint film at the 24 inch pound level of impact. Rust Bullet exhibited cracking of the paint film at the 28 inch pound level of impact.

Did I mention Rust Bullet is a SINGLE step (2 coat) process also. And comes in Any color you want as long as it's METALLIC-GREY. We do Rust prevention, not color paints.
