I placed an order from 4statetrucks.com for a 8" green airway wheel, and two 8" white wheels. I also ordered the Zephyr green rouge, white rouge, and blue rouge. I used the green wheel and the green rouge, wiped down with Pro 50 eliminator, then used the white wheel and white rouge, wiped with Pro 50, then finally the other white wheel and the blue rouge followed by Pro 50. Final hand polish and protect with the Pro 40. Less than a hundred bucks worth of materials and 30 minutes on the first wheel. Pretty quick process actually.
If your wheels are pretty rough to the touch, you may have to start with a yellow wheel and brown rouge.
I ran all of these wheels on 7.5" angle grinder. Just make sure you use safety glasses and a dust mask!
