No its really cheap, Tap plastics sells it. I think you can buy it online if there isn't a retail store close.
I got the tank for such a good deal, I thought a little elbow grease was worth it. The drill made the big difference.
There are three stages:
One is just a cleaner, and gets the gunk off of the acrylic.
Two is a scratch remover. This is the one I used the most with the drill, If you can see scratches or discoloration, use this. Commonly caused by cleaning the tank and having some sand on your scraper.
Three: a little more hard core, if you can feel the scratch with your fingernail, then you use this bad boy. I didn't use this inside the tank, but I did on the finish of the outside. I only got good results when I used it with the drill and the buffing pad. Also the 5000 grit wet sandpaper helped a lot on the scratches on the outside.
It looks brand new after all the buffing. It took about three days in about 4 hour increments to finish the whole thing but it was worth it.
THEN I added a 180w light to the tank and algae attacked my beautiful clean acrylic!!
