I do have a router if you want to use one. Same idea. Clamp a straight edge and run the router along the guide
doing that tank with a router is the way to go.. clamp your straight edge above of the bad side.. 3/4" should be good rimless up to about 22-24" high safely.

2 flute slow spiral solid carbide bit if you have a choice, otherwise a quality carbide tipped 2 flute straight cut will also give good results and minimize final finishing. Number of passes for 3/4 cell will depend on both the router and the bit.
Since heat stays localized it's better to keep the feed rate or speed of you passes fairly high to prevent melting rather than slowing the cutter speed.
