I know its not what you guys are looking for. But there is a product called Amerlock 400 from PPG that essentially does the same thing as POR-15 but does it better. Requires less way less prep, can be put on top of rust, the surface can even be partially wet and full adhesion will occur.
Amerlock®/400
A self-priming epoxy with full color availability, combining high-performance protection with ease of application. Amerlock/400 provides a simplified solution to complex plant and offshore corrosion problems. It can be applied to tightly adhering rust and old paint surfaces – without the need for blast cleaning – and still delivers a high degree of chemical and corrosion protection where surface preparation can only be minimal.
Advantages:
Amerlock’s low solvent level meets VOC requirements, reduces the chances for film pin holing and solvent entrapment at the substrate-coating interface.
The superior wetting action of Amerlock/400 permits excellent adhesion, thoroughly soaking into the rust layer and tightly bonding to the underlying metal.
Amerlock/400 has good chemical resistance to splash/spillage, fumes and immersion in neutral, fresh and salt water.
As a maintenance coating, Amerlock/400 protects steel structures in industrial facilities, bridges, tank exteriors, oil tanks, piping, roofs, water towers and other exposures.
