QuikTrip center - New roof every 3 years?

[Conan71]

Based on experience I've had with cosmoline on surplus military parts, petroleum products can be good to help preserve metal, but if water gets underneath the protective coating, grease or cosmo will trap the water against the metal and allow corrosion and pitting.

Don't forget "Cosmolene" was supposed to preserve a certain car.
