I have a 2000 Jeep Cherokee Sport. The front and back bumpers as well as the side body molding are black plastic. The plastic has become dulled from the sun and I was wondering if anyone has any experience repainting these and would be willing to share the process. Is it as simple as removing the parts, light sanding to open the pores, cleaning them with denatured alchol and painting them with Rustoluem or Krylon product made for plastic or does it require the equipmnet found in a pro body/paint shop to complete this task ? Any feedback would be appreciated. Thanks.  

oohh u know what my 2000 grand cherokee had the same mess and i took it to a body shop and they restored them not to the original condition but they looked good but now 2 years later i'm getting new ones because they are dull, ugly, and well have some damage again except the ones on the sides they still look ok  

I have used the Krylon "plasticoat" many times on plastic parts for the home as well as for the Jeep.. Even got a complement from Krylon themselves.

The main thing your dealing with while using a product like krylon, is the fact the surface area which your going to paint needs to be very clean and sanded. then Primed and sanded once more.. A "prepsol" tackie rag would then need to me used in this instance to remove and dust and then one can mask off the area or if one has the time completely remove the part from the vehicle. Personally I would prefer to remove the part from the vehicle and complete the stages listed above. sanding etc..

The next issue you may face is the weather mainly the humidity.. The can states 70 degrees or around that for a proper coat to adhere to the part. You may need a dehumidifier set up in your shop to draw out the moisture in the air or even a heater to speed up the drying time between coats.  Never spray in one spot as to allow the paint to "build up" an uneven area or runny spot. Sure One can paint anything.. and one doesn't need the expensive sprayers the auto body shops have.

I mean if your going to do a few simple jobs then you don't need a big system for the job. The spray can and proper care is all that is required.
