Its a very good clay.

What's the average price for clay, are they all around $20 or can you recommend one that's cheaper. Thanks.

Trust me, the Mothers clybar is the best all around deal. It's not REALLY expensive, but it isn't some cheapo brand. I beleive they were the first to start marketing them, so they have experience. Couple of tips, ALWAYS make sure the surface area is lubed up fin, might want to get a second bottle of the cleaner, which is good for getting bugs and tar off too. Place towels around the area you are claying, because as soon as it hits the ground, it will pick up rocks and small particles, and is cashed. Also, make sure you wsh the caragain before applying any polish/wax/zaino because the mothers will leave a film frm the spray. Hope this helps.
