Yeah, it can make a difference, but the key to it is what you are trying to use it on. For striping, a good Aluminum Oxide like a 120 grit is a good choice, unless it is a soft surface. Then, you can step down from glass bead to walnut shells, and some people even have success using talcum powder for really fine finishes. There are a lot of people on here more knowledgable than I am to ask, but compared to the playground grade sand, I think you'd be happier with other options. Best of luck with it.
