Dear Mr. Know-It-All, Where can I have two sections of stainless steel tubing chromium-plated in Hong Kong? If you ride a Harley in Hong Kong, as I do, sometimes you have to make your own shiny bits. That’s not too difficult, but making them really shiny—and protecting them from Hong Kong’s somewhat corrosive atmosphere—means hard or satin-chrome plating. – Biker Barbender There’s a tricky one. I ride a vespa myself, so chromium plating has never been much of an issue for me. For Harleys, you can certainly try Techno Harley Division of Hong Kong (A5, G/F, Sha Tin Industrial Center, 5-7 Yuen Shun Circuit, Sha Tin, 2806-8444, www.harley-davidsonhongkong.com ) I called the shop and they offer what you’re looking for, but they’ll need more information from you, such as what model chopper you have and what kind of tubing you want, to see whether they have a suitable type of tubing for your bike. And just for your reference, the Chinese word for chromium plating is 鍍鉻., pronounced “doh gok”. Ride on, cowboy. Dear Mr. Know-It-All, My laptop screen is horribly dusty, and screen wipes just don’t cut it. Do you know where I can get a proper aerosol cleaner so I can finally see my screen again? - Dusty Data Cruncher I completely understand your plight. A feeble swipe of a tissue does nothing but spread dust and cause untold misery to the poor saps spending 12 hours a day hunched over their PCs. Fortunately, help is at hand. Pick up an aerosol cleaner at Computer House in TST (Shop L73, Peninsula Center, 7 Mody Rd., Tsim Sha Tsui, 2369-2225, www.computerhouse.com.hk ). It sells spray cleaner for $50-$60 per can. Alternatively, the computer geek’s haven of Sham Shui Po always has some good swag. Centralfield offers the spray at around $50. Find it at Shop 98, 1/F, Golden Computer Shopping Center, 94A Yen Chow St., Sham Shui Po, 2387-0273.
