A sand blaster will work, but it can change the finish on the concrete and be almost as visible as the parking stripes. I would only use a sand blaster if I just wanted the stipes gone and the rest didn't matter.
True but they use a lot of product for sand blasting these days that isn’t sand, but hard enough to remove paint. I saw one site where the guy said he was using hulls. I didn’t ask any more, and it seemed to be working well however I haven’t been back to see the finished job.
