You can clearly see this truck is kept very clean. Recently had a rain storm and got that built on rain grime. First I’ll say that the bottle doesn’t just foam up. You have to shake the bottle in your hand while spraying for it to foam up.
Next it does absolutely nothing. You can see hear after I foamed it and let it sit and rinsed it off, I ran my hand on the paint in a circle and that’s cleaner then the foam made it. This stuff is pure crap and snake oil.
