Absolutely true. The surface texture will be removed, it does not matter if it is smooth.
Why the 600, 800, 1000, 1500? It only takes a few minutes using only 2000.
Anything less than 1500 is doing damage.
Better yet, don't hold the gun over the tank, if you have to for some reason stop first and get a rag to catch anything.
You want to cut through the clear as quickly and smoothly as possible, especially if it's a slightly dry finish to begin with. You can start with 800 if it's pretty smooth. 2000 doesn't really do that alone, it's not coarse enough. 600-800 flattens it out immediately, then the finer papers prepare the surface for the 2000, which basically all it's doing is polishing the surface at that point. Less will be taken off in the long run if you're careful. You might try only filling the cup half full if it has a tendency to leak..or better yet, most metal cups are only about 25 bux, cheaper yet for a plastic one. Save the anxiety and cost of drips by just replacing it.
