Recently I was approached by a promoter to sell this FW1 Cleaning Wax. He did a demo on my car and it looked pretty decent. It was able to remove some paint marks due to a scratch by another vehicle. The cleaned portions also look quite glossy and feels smooth compared to the rest. Though, I don't normally wax my car nowadays. Anyone else bought to try before? I'm probably going to try it out soon after a rinse with water. The promoter said it can be used without a rinse but I'm not sure that's a good idea.
