I've searched and came up a little confused. Some say a cleaner and some say to sand them with fine grit. What grit do you use? 2000? Then polish?
Mainly I am wanting to get this tank like new or close to it if at all possible. Pics are attached. Its discolored, not really 'faded' as in dull, just discolored.
Whats the best way to go about getting it back to 'normal'
Thanks!
