If you smell gas coming from beneath your car, never check under it with an ordinary strobe light. If any gas falls on the lightbulb, it could explode and cause a serious fire. Use a light with a protective surface instead. I have found that if you put peanut butter, preferably not chunky, on glass, bottles, or even mirrors, it will remove the residue. Sometimes it takes more than one application.
Most people have peanut butter on hand.
If you ever get a leak from a cracked gas tank on your vehicle, the temporary solution is to scrape a bar of soap on the crack till it seals. Just spray them with Dow bathroom cleaner and let them dry. To quit smoking with out use of expensive drugs you must be motivated. To become motivated obtain from the American Cancer Society coloured pictures of healthy and tainted lungs and bladders and all available reading material on causes of lung and bladder cancer or purchase a medical book from your local book store and read the causes of lung and bladder cancer. After you decide to quit, carry a supply of common plastic swizzle sticks and when you have the urge for a cigarette hold a swizzle stick in your fingers, play with it and chew on it a little.
