"Famous Green Label surf wax is a true 100% petro-chemical free, organic, biodegradable, high performance surf wax. Geen Label wax also features certified recycled packaging with soy ink. Made in the USA and part of the Project Blue initiative, a portion of the proceeds from Green Label surf wax goes to the Surfrider Foundation."

It's only 50 cents more than sticky bumps, and its traction is the same or better than anything else I've ever used. I found it in Farias in Ship Bottom a while ago, most stores probably carry it. I would definitely recommend this over anything else unless you're really into the idea of making your own.
