[EX Q]: [header] How to remove paint from a car exterior [title] Park the car on top of a large tarp or drop cloth to contain the old paint. [step] The old paint should be disposed of instead of letting it contaminate the ground. If an open area is not available, park the car inside a garage, but open all of the garage's windows and doors for ventilation. <sep> (A) Cover objects inside the garage to protect them from the paint dust. [title] Use masking tape to cover the areas of the car that won't be sanded. (B) Alternatively, use a flashlight to check beneath the tarp. [title] Use an old baseball bat, crowbar, pry bar, or other large object to push the old paint off of the vehicle. (C) [title] Wipe the paint with a wet cloth, a roller wrap or an old towel to protect it from oil and water. [step] The paint is likely to collect on these cloths and make them easier to clean as they are removed. (D) If your garage is not well ventilated, a ventilation device will block your windows when the old paint has dried to a mud-like consistency.

[EX Q]: [header] How to get rid of a scab [title] Make sure the scab is not oozing. [step] Before you can properly dress a wound or scab, it should be dry. If your wound is oozing blood, place some sterile non-adhering gauze on it. <sep> (A) If it soaks through the gauze, don't remove it. Removing it can restart bleeding by pulling off the healing tissue. (B) The gauze will avoid soaking in blood and leaving you with a clean scab. [substeps] Avoid applying a bandage to blood on a scab once it has dried. (C) You can also apply corn syrup on top of the area. [substeps] The gauze should cover the wound completely, so no blood soaks into it, though it will not bleed through if it has. (D) Make sure there is no dripping liquid onto the surface or the area will not stay intact. [substeps] You should also avoid touching the wound, as it is your medical job to protect it and heal.
