This little Chevy truck came to me with pretty severe sun fading on the fender skirts.  Painting plastic parts requires a few different steps than painting metal.  I have to make sure the paint will stick to the part and also that it will be able to flex without cracking off.  I have additives that I add to the paint as well as special primers for that purpose.  This job turned out great and the owner was very pleased.  The value this added more than made up for the cost.  This is very important if you are planning to sell a vehicle.  You can spend a little up front and it will make the car or truck a lot easier to sell, plus you will get more for it.  This is exactly the kind of work I do for many car dealerships for that very reason.
