Before using a clay bar on your vehicle, it's essential to apply a lubricant to ensure smooth operation and prevent scratching the paint. Here are the key points regarding what to spray before clay barring:

1. Clay Bar Lubricant: The most common product used is a dedicated clay bar lubricant, which is specifically designed to provide a slippery surface for the clay bar to glide over. This helps in effectively lifting contaminants without damaging the paint.

2. Water and Car Wash Soap Mixture: If you don't have a dedicated lubricant, you can create a mixture of water and car wash soap. This can serve as an effective alternative, although it may not be as slick as a commercial product.

3. Quick Detailer: Many clay bar kits come with a quick detailer that can also be used as a lubricant. This is a convenient option if you're using a kit.

4. Fallout Remover: For enhanced decontamination, you might consider using a fallout remover (like Car Pro Iron-X) before applying the clay bar. This step can help remove embedded contaminants more effectively.
