Backpacks are often the most convenient way to carry your gear, this one is specifically designed for flying with dedicated radio pocket, headset pocket and space for fuel testers and more. For a limited time it comes with a free water bottle holder. Makes a great gift for the Student Pilot starting out this fall.

Rust occurs naturally when the iron in steel oxidizes and returns to its original state, iron oxide. Through an innovative chemical conversion process, Corroseal Rust Converter converts rust (iron oxide) into a stable substance, magnetite. It also primes the surface with a high quality latex metal primer at the same time.
