This morning it got a coat of Ospho to neutralize the rust.
Started with this.
The Ospho turned it to this.
While that was drying, I spread all the media used yesterday, on the drive way.
Lunch, a few trips to stir it, and a nap later, I recovered most of the media. We ran it through 3 consecutively smaller screens to remove all the trash and paint chips. I shouldn't have to buy any more to finish the other side of the bus.
After that, the Ospho was dry and it was time for primer.
This is not going to be a show quality paint job. This is a stop the rust and be durable paint job.
Today was a good day. More to come.
