In one sentence, describe what the following article is about: Spray paint and primer can cause skin, eye, and lung irritation. If you start to feel nauseated or lightheaded, leave the area immediately and contact Poison Control for further instructions. Paint in a well-ventilated area to further avoid irritation. Wrap your tire and any areas of the rim you won't be painting with kraft paper, and secure it down with masking tape to make it stick. Metallic spray paint can be tough to remove, so protecting as much of your wheel as possible will prevent accidental staining. Only the damaged areas should remain uncovered, as you don't need to paint the entire rim. A primer will help the paint look more natural and allow it to stick to your rim better. Stand 68 inches (1520cm) away from the rim and spray the damaged area in sweeping motions. A single coat of primer is enough to help the spray paint stick evenly. Check the primer's instructions to see how long you'll need to let it dry before spraying the paint. In general, the time should range from 30 minutes to an hour. Do not spray paint until your coat of primer is completely dry. Choose a spray paint color that closely matches the alloy rim, which should be silver. Hold the spray paint can 1012 inches (2530cm) away from the rim's surface and paint the area with a sweeping motion. Waiting 30 minutes to an hour will help your coat look smooth. Avoid touching your spray paint as it dries to prevent smudging it. For exact drying times, consult your paint's instructions. After your coat has finished drying, apply additional coats until you reach your desired color. In most cases, you will need to apply at least 2-3 coats for a natural-looking repair. Let each coat dry for 30-60 minutes before applying another one. Do not touch the paint between coats. Paint lacquers will keep your spray paint from scuffing or flaking away. Spray the lacquer in a light mist, similar to how you applied the spray paint, then let it dry. How long you let it dry depends on the lacquer but generally ranges from 8-24 hours.
Summary: Put on goggles, a respirator, and gloves before priming or painting. Mask your wheel with tape and kraft paper. Spray a metal alloy primer over the damaged area. Let the primer dry for 30 minutes to an hour. Apply a base coat of metallic spray paint to the damaged area. Let the spray paint dry for 30-60 minutes. Apply 2-3 additional spray paint coats. Apply a spray lacquer to seal the paint job.

Use a yoga or gymnastics mat or a mattress, or clear an area on a soft carpet or rug. Make sure your area is clear of any tripping hazards, such as small objects.

Q: There are many sites that offer online piano instruction. Find one that works for you by looking at several sites, and comparing their features. Great online sites may offer users the opportunity to 'sample' or 'try' lessons before buying a subscription or paying for lessons. Examine the site and the piano lessons to confirm that they seem professional, thorough, and genuinely educational. Since any individual can start a piano-instruction website, you may want to take some time to vet the website for security issues. Look at the site's security policy. In the anonymous world of the internet, this is extremely importantyou want to be sure that the person who created the websiteand who you may be paying for their serviceis safe. In the first couple weeks of lessonsor even before lessons start familiarize yourself with the technology that the website uses for instruction. You may need to download a new media player or use audio or video files you're unfamiliar with. Also familiarize yourself with how the website handles the logistics of scheduling and paying for lessons or instructional material. Consider: Does the site let you schedule a set of lessons up-front? You don't want to keep having to add things to your calendar and then forgetting. Can you get discounts when purchasing packs or lessons in bulk? What is the site's cancellation policy? When making a payment, how secure is the site? In the event of technical problems, how responsive and extensive is their customer support mechanism? Many websites that provide piano instruction will offer different "levels" of subscription, ranging from "basic" access, with limited features, to "premium" access, with extra perks and bonus features. Consider if you need the extra features, and choose the level of subscription which best suits your goals. If you're indecisive, start with the cheapest and most limited subscription level. You can always upgrade to a "premium" level, but it may be difficult to downgrade to a cheaper level. Must instructional websites will route you from simple lessonssuch as identifying keys on the piano and playing a couple of scalesto more complex lessons, including playing with both hands simultaneously and learning all 24 major and minor scales. If the option is available, it could also benefit you to learn some music theory. Even if you're not planning to compose your own music or to analyze chord structures, having some theory knowledge will help you to better understand the music you're playing.
A: Find a trusted website. Investigate the logistics of the website. Choose a level of access that suits your goals. Start with the basics.

Problem: Article: Gaining access to your computer's heatsink and/or CPU will vary depending on what you have. Refer to its owner's manual to find out how to identify, access, remove, and reinstall the necessary parts. If you don't have a hard copy, search the manufacturer's website for a copy online. Once you have safely removed the heatsink, get rid of any dust in its vents. Use a small brush and/or a can of compressed air. Be sure to do this well away from the computer's other parts so the loose dust doesn't end up where it doesn't belong. Find the heatsink's copper cores. Scrape away as much of the old thermal paste as you can with the flat end of a spudger (a small handheld tool used to manipulate computer components). However, you obviously want to be careful not to scratch any parts, so if you're nervous about this step, feel free to skip to the next. Alternatively, you could use a dry cloth or paper towel to rub off most of it if you're worried about scratching the components. Even if you used a spudger, don't expect it to get rid of the old paste entirely. Whether you skipped the previous step or not, grab some coffee filters, lint-free cloths, or q-tips. Wet one with either rubbing alcohol or a cleaner specifically designed for thermal materials. Then use the wet end to moisten, loosen, and remove the old paste. Repeat as needed with fresh filters, cloths, or q-tips. After all traces have been removed, repeat this step once more to get the surface ready for a new application of thermal paste. Cleaners designed for this specific purpose are usually labeled as TIM cleaners (thermal interface material). Inspect it for any thermal paste where it came into contact with the heatsink. If you find any, use the same steps to clean the surface. However, if you use a spudger to scrape the old paste away, only use a plastic one to reduce the chance of scratching or otherwise damaging parts. If you don't have one, don't attempt scraping. Be especially mindful about where the old paste ends up. Once it's loosened, you don't want to accidentally brush it off so that it ends up lodged elsewhere in the processor. If your last application of thermal paste dried to any other parts, use the same method to clean it up. However, use q-tips, paper towels, or other soft material rather than a spudger, since other parts may be more fragile. Additionally, try using a compressed-can of CFC (chlorofluorocarbon)-based automotive electronic contact cleaner if the paste has dried in thin, hard-to-reach gaps.
Summary:
Refer to your user manual for access. Dust the heatsink's vents. Scrape off old paste. Rub away the residue. Repeat with the processor. Do the same anywhere else thermal paste has spilled.
