I've done it with a 20 long I got for free . Great tank except all my tanks are black rimmed and this one was 'oak' . So I lightly sanded the trim with something like 320 paper , masked everything off with blue painters tape and newspaper and hit the trim with some Krylon Fusion. Took care of any overspray with a kitchen Scotchbrite after everything dries . Been a few years , no problems . Matches the other tanks pretty well .
