the dupli color "paint shop" is what me and a friend of mine used to paint his truck.
it was very easy to apply in 3 easy steps, and only cost around $200 to finish.
we did it about a year ago and he takes the truck wheeling and on trails all the time, and still no scratches or blemishes in the paint.
It looks great and will last. im going to do my truck with it here in a few weeks. Plus, it's only $30 a can, so you can't get any better for the money.
also remember, 85% of a good paint job is preparation. so don't skimp out when it comes to sanding and other pre-paint body work
