Unfortunately, I didn't take any pics of the process. I used an orbital sander with sheets of 3m from 400 all the way to I believe 2500 was the highest that TAP plastics carried. Then I went from hand with micromesh from 3000-12000. I was talking with james at envision a short while after completing it and told him it would have been nice if I could have got larger sheets of micromesh to use in the orbital sander and he said that they were available, you just have to call and ask for them.
If it were me, I would call and get full size sheets of micromesh and use an orbital sander, I don't suspect that they will be cheap though...but neither is a new tank,lol. You can borrow my dewalt sander and buffer if you want.
I think that if you use the right sandpaper and right tools, it could go pretty fast, but may cost a bit.
Here is a bad pic of the whole tank after setting up...cant quite get the white balance right with my current camera...need a new camera for christmas,lol.
