Dustless blasting: whole car paint removal in 1 hour

If you watched the video at the end after blasting they treat the whole car with a coating of some sort prob to inhibit rust be my guess..looks like a good way to go but a thousand dollars to blast a car seems a bit much..I'm all for making money but just think how much more you could make by doing a couple a day for say 500 bucs,be more likely to attract more customers as it would be more affordable,and you could always lay a tarp underneath to catch residue and bag it so as to no bitchin about the runoff and enviromental issues..
