Instructions
Abrade the acrylic where the scratches appear using 800-grit sandpaper. Continue sanding until the scratches are gone or appear barely visible. A film from the sanding will appear.
Wipe down the surface thoroughly with a tack cloth after it has been well sanded to clean off any dust.
Sand the same area using 1000-grit sandpaper, making the surface smooth and rubbing out any traces of the scratches. Another film will appear while using 1000-grit sandpaper. Clean the film off with a tack cloth.
Treat the area you sanded with a polishing compound. Use a clean polishing rag, rubbing on the compound in a circular motion. Immediately buff the polishing compound into the acrylic with a buffer while it is wet.
Dab on plastic polish cleaner with a clean cloth and buff over the acrylic tank once again with the buffer until the cleaner disappears.
Wipe down the entire tank, concentrating on the repaired area, with a clean cloth to finish the job.
