If you use this product as directed, "a light dusting", one can will last a long time--several short-course bodies. It doesn't go on like spray paint in that you need to apply from further away and in much less quantities. Don't use the color change paints without it. If you tend to "over do" this will run and make swirls in your paint--only reason I'm not giving it 5 stars.
Just got done doing a mirror chrome top and must have used too much or too close because the prep spray left it foggy in areas, I'm still pleased with the end product but will try to do this paint job without the prep spray and just wash the top with dish soap.
