The kits that I've seen all have a lot more than enough of all the grits but the 80 grit which is used to grind out the hole in the glass. That can be easily replaced at a sandblaster for a bit less than what any astro grit place would be able to sell you. You don't need good grading of that grit as the next grit will get rid of any bigger pits from large grains in the 80 grit.
