spray paints

I need to paint a few patches on my car before i sell it.

has anyone bouht paint, or know of anyone, from paintscratch.com

they have my color in stock in a spray can form. i was considering getting it to cover up my primer spot and repaint my bumpers. i just want to know how good that stuff is. bear in mind, im trying to sell it, and currently the cars paint is a little faded, it looks as though the clearcoat has worn off.

or should i just get a regular can from a paint shop around me and use a sprayer?
