Sandblasting

[Theoriginalsilverado]

Hey guys!
So I'm planning on renting an industrial sandblaster to sandblast my truck. It's $300 for one day. I'm planning on renting it for one day and blasting my whole truck. I'm going to use glass beads for the project.

My question is how much media will I need to sandblast the whole truck? When I say the whole truck, I seriously mean the whole truck. The chassis is empty- no motor no cab no bed. I'm going to blast the chassis, rear end, cab- in and out, the bed (which has a wooden floor so I don't need to blast the floor), all the suspension except for the rear leafs which is already done and painted. I may even blast my rims and engine block, depending on if I reuse my rims and if I have the engine ready for that by then.
