I am having a hard time tracking down Acetone in Hong Kong. For those unfamiliar, Acetone is similar to paint thinner - it is a strong chemical solvent. I have checked some stores in Mong Kok as well as Sham Shui Po but have had no luck. In the United States, this is typically sold at hardware stores such as Lowes, Ace, Home Depot, etc.
For reference, I live in Clearwater Bay so any suggestions on the Eastern side of HK are appreciated, but I have no problem traveling a little to find this.
