"Hi, it's Dow here at the Firehouse Car Wash and Detail Center. We're talking about an exterior detail on your car. Previous segment we talked about evaluating the paint. Figuring out does it have overspray, does it have scratches, are there swirl marks? Black cars in particular show a lot of these imperfections in the paint as do a lot of the dark colored cars. This is an area where it's difficult to train in a short segment the complicated nature of doing this, and it's going to be the one place where I step in and say in most cases you're going to need to seek professional assistance in removing scratches, oxidation, paint imperfections, swirl marks. As you can see it's a pretty complicated process. We're going to be use a high speed buffer. Quite simple to burn through the clear coat and into the paint. We've got multiple different pads depending on the level of damage to the paint. So we're going to go through different pads and the coarseness. We've got different products, aggressive compounds that will lift scratches out. When all said and done, your car is going to look beautiful. There's nothing more distressing to a car owner than to come in and find a professional detail shop using sand paper, wet sand paper on the paint. We actually wet this sand paper and we'll sand out scratches cautiously on the clear coat. It's amazing the kind of recovery we can make to paint where maybe it's been scratched from a four wheeling trip, a child rubbing dirt on the side of the car, where you thing the only option is repainting, it's often for a hundred or several hundred dollars we can restore the paint back to as new condition. So I would caution you against grabbing a buffer and going to work on your car all by yourself. This is an area of professional, but we use these kind of compounds. We use a cut, an extra cut, maybe a medium polishing compound, or even a clear-coat polish like this that just brings the luster and shine back in the final stages. Whatever it is, before you jump in with a buffer, seek professional advice in this area, but know that your car on a detail can come back to a like new finish."
