Sandblasting might be old school but theres some old school guys out there that can get it done.My suggestion is DON'T have it "sandblasted". Sand blasting can, and often does RUIN a car. It will DESTROY panels if done incorrectly. And YES even "Pros" RUIN cars.
There are many products you can "blast" a car with, sand is old school and honestly will RUIN a car, warping the panels beyond repair. So be VERY, VERY causious about who you drop your car off with.
Billy is good! he's near my house!There is a place in Spring that does media blasting. He will also epoxy prime it also. His name is Billy. I have used him many times. Hopefully he is still in business.
