I have a soda blasting business in Australia, and I keep hearing all this carry on about failed paint jobs
, but its all Chinese whispers. I have blasted hundred’s of cars and boats with no failures. Yes you must prep the car properly, blow the car out with air, wash the car with soapy water, dry the car with air and scuff the surface with a scourer and then wipe with prepsol. And you will have great job.
