I recently repaired some damage on my car, which isn't quite done - I still have to scrape the runs. However, the paint is a significantly different shade from the rest of the car. I asked to have the codes matched, so I assume it's because of fading. Is it possible to mask off the old paint on my car, and put a UV light on the new paint to force it to fade quickly? And roughly how much power would I need to get anywhere? I found a 400w black light on ebay, but I have no idea how that compares to the UV the sun hits my car with. Thanks!
