Its a grand idea but just dont forget that the material goes absolutely everywhere and needs to be cleaned very thoroughly.
Technique and pressure is everything as is the media used.
Dont forget glass will become opaque and that the media is everywhere.
We have a vehicle that was sand blasted, lenses for headlights were nailed, bins full of sand even after painting, the level of care shown on that vehicle being put together before we purchased it is awful, this is just a small part of the nightmare it continues to be.
