Crappy stock paint is something we all are going to have to deal with. We are basically left picking the color we really want (however low quality that may be), or settling for another color that won't show imperfections as well as other colors. When I buy my Mustang I'm going with Vista Blue, however I don't like the quality of the color at all - I've always wanted a blue mustang with eventual white dual lemons strips.
What you can do to fix the low quality/protection of your current steed's exterior, is invest in high quality cleaning/protectant products. Two products come to mind (after exstensive forum searching both on this site and others), Meguiars and Zaino - I just spent $108 ($16 including tax/shipping) on Meguiars. This includes all claying, cleaning, polishing, washing, waxing products I'll need for the exterior, plastic trim, aluminum rims, and tires of my 96 Jeep Grand Cherokee Laredo - also included in the price were numerous washing/drying towls, a tire brush, and applicator pads. Time to start practicing for the Mustang

I bought the wax at a local auto zone to try out the line (Meg NXT liquid wax) and it REALLY made an improvement, I now am able to clearly see the orange peel were before it was so filthy you couldn't see anything

! I plan on taking before and after pictures and will post them so you can see how this line works on handling beat up, old, poor quality paint jobs.
