Getting the rust out of the inside of the rockers would have been impossible without sandblasting. With the new compressor sandblasting was a lot smoother. No need to wait for the compressor to catch up. Only downside is that sand gets EVERYWHERE. Between the sand and the paint fumes the garage wax toxic. I had my respirator on until the last minute before running out the door.

After blasting i spray painted with eastwoods rust encapsulator.
