Have you ever been confused about when to use a clay bar and when to use a compound? Have you wondered what each step does and what the difference is between the two? With a little knowledge you can understand the difference between the two and know when to use a clay bar and when to use a compound. Start off by washing and drying your car with a premium car wash like McGuire's ultimate washing wax to remove any loose dust, grime and debris from the paint. Be sure to use premium microfiber accessories to get the best swirl-free results. After washing and drying it's time to evaluate the paint. Run your clean dry fingertips over the paint. If it feels rough this indicates that you have bonded contaminants on top of the paint that need to be removed. These are things like rail dust, tree sap mist, industrial fallout and paint overspray. If your paint feels completely smooth to the touch upon evaluation you can skip this step and move on to compounding. McGuire's currently offers two clay bar kits. McGuire's hybrid ceramic quick clay kit and McGuire's smooth surface clay kit. Both kits quickly remove a buff surface bonded contaminants without swirling or scratching, make the paint feel as smooth as glass and allow for the next step to work quicker and better. Hybrid ceramic quick clay kit makes use of a synthetic clay pad and McGuire's hybrid ceramic detailer as a lubricant. Glide the lubricated pad back and forth until the paint is smooth and wipe off the excess with the included Supreme Shine microfiber. Work in sections over the entire vehicle. With the smooth surface clay kit you spray section of the paint liberally with the McGuire's quick detailer, take a clay bar and flatten it like a patty, spray once with the detailer and work it back and forth until the paint is smooth. Wipe off the excess with the included Supreme Shine microfiber. Again, work in sections. Another option is McGuire's iron removing spray clay which easily removes embedded iron contaminants from your vehicle's paint surface like rail dust and other industrial fallout. After washing and drying your vehicle simply spray the product onto a small section of the paint surface and gently agitate with McGuire's microfiber washman, rinse and dry. On lighter color vehicles you will notice the product reacting with any iron contaminants and turning a bright purple color. While McGuire's iron removing spray clay works to easily remove common iron based contaminants from your vehicle's paint, it is important to note that any other environmental contaminants which make your paint feel rough like tree satin mist and paint over spray will need to be removed with the traditional clay bar or synthetic clay pad like McGuire's smooth surface clay kit or hybrid ceramic quick clay kit. For this step, visually inspect the paint for below surface defects like swirls, scratches, oxidation and stains. Different types of lighting can reveal different defects, so consider looking at the paint from several different angles and in different types of lighting so we can see all potential defects that may be present. If you have light to moderate below surface defects, McGuire's ultimate compound is the perfect way to remove defects in the paint without hazing or marring the surface like a traditional compound. Apply a small amount of ultimate compound with a soft foam applicator by hand or with a foam cutting disc by DA polisher. Work in a 1 to 2 square foot area with overlapping passes using light to moderate pressure. Wipe off the residue with a premium microfiber towel before it dries. Make sure your work and reapply is needed to remove any remaining stubborn paint defects. Work in sections over the vehicle. Once you're done, apply McGuire's ultimate polish for maximum shine followed by your favorite McGuire's wax to ensure you have plenty of protection on the paint. So the next time you notice your paint doesn't feel completely smooth or if you notice swirls, scratches or stains, you'll now know the difference between a clay bar and a compound. You'll know exactly which product to go to for each specific issue. This will help you get the results you want so you can keep your car looking its best.
