and if you didnt wash the car before dropping it off, you could see the dirt under the paint and on top of that, if you didnt pull off your molding, it would be painted to match. :gaah: Atleast that was the experience of a couple of my friends.
If it was me I'd go down to the local parts store and buy a spray can of the stock color, you could probably paint the whole car for under 100$, of course it wont be the highest quality but it would cover up the parts that are rusting, just make sure to sand the rusted spots down to bare metal, and use a primer first. If you want to keep the job small, just buy the paint in a can and apply it using a paper match.
One other option is find a junk yard, with the parts you want painted, that are already the stock color and in better condition, then just replace your chipped parts. You could probably find both fenders, the bumper, and a hood for around 300$, just ask for the front clip. It might take a bit of time to find junk yard parts that are in better shape than yours though, but it is possible.
