yung acrylic side panel nung case ko (thermaltake corev21) has accumulated a hefty amount of scratches after a year and a half.

i researched kung paano ma-remove yung mga scratches, and only one brand of polishing agent has always come up which is: Novus

meron sa lazada kaso parang sobrang pricey for me as of the moment.

just wanted to ask if may alternative ba dito sa pilipinas. what do you guys use to buff your panels?

thanks po in advance
