I blasted it also outside in the driveway of our trucks park. Luckily this is a gravel driveway.
Neighbor still didn't come complaining
It doesn't work as quickly as a thought. Compressor blow air like hell, but the blaster is a hobby type. The bus had been painted 3 times. Original paint come out quickly but the last layer is a thick paint and they used a bondo style primer. I will blast the inside, door jambs and I will did the flat large exterior surfaces with bristle discs.
