Repair 7

Single stage urethane enamel is a type of automotive paint that is commonly used because it does not require a clear coat, thus reducing costs and the time needed to paint the car. While this is one of the most common and durable types of paint available, it is still susceptible to damage, and you may need to repair the paint on your car. There are many products available that make a small paint repair simple.

Instructions

1

Repair any dents and remove any rust. Wash the area to be repaired with dish soap and water. If the damage is fairly extensive, you may want to sand the area, as well. Soak some 600 grit sandpaper in cold water for 10 minutes, then sand gently. It is easy to sand off urethane enamel. Wipe away dust afterward.

2

Mask off the area by taping newspaper pieces around it with masking tape or automotive masking tape. This prevents excess paint from getting onto undamaged areas of your car. If the damage is extensive and goes to bare metal, spray the area with at least three coats of primer and sand again. Wait for 30 minutes before continuing the repair.

3

Paint the area with automotive repair paint. There are several types: pens, bottles and spray cans. Pens and bottles are for very small repairs and cans are for larger repairs. If you are using a spray can, apply the paint in several light coats, waiting for the paint to dry completely between coats. Try to blend the edges of the paint into the old paint.

4

Apply a clear coat over the repaired paint. This is necessary for a large repair. Use several layers of clear coat. Once you have applied the last coat, wait 24 hours, then apply rubbing compound.

5

Remove the masking tape and newspaper.

The performance difference in single and dual-exhaust systems is solely based on the amount of evacuation produced. Although two pipes can evacuate more exhaust, a single exhaust system with larger evacuation pipes provides the same performance.

General Information

Each cylinder in the engine has a pipe extending from it for exhaust. All pipes are joined into one pipe as an exit point that connects to the systems head pipe. The head pipe joins with the catalytic converter, which converts toxic fumes to reusable air. The catalytic converter then sends the exhaust through the muffler, which acts as a second filter, sending the remaining air through the tail pipe.

Single Exhaust

Single exhaust systems have one catalytic converter, one muffler and one exhaust pipe. They cannot be converted into true dual exhaust systems because smog regulations do not allow catalytic converter changes. When properly configured, a single exhaust system is just as productive as a dual.

Dual Exhaust

Dual exhaust systems are either true-dual or split-dual systems. The true-dual exhaust includes two catalytic converters, two mufflers and two exhaust pipes. The split-dual system has one catalytic converter, one muffler and two exhaust pipes. According to Flow Master Mufflers, dual exhaust systems increase engine power, use gas more efficiently and reduce engine noise.
