How many square inches?
If you vehicle is black, or very dark (black is easier the Kandy colors are invisible over black or the navy blue like my Stratus) you probably will need to get some paint to match your paint.
If you can clear coat it your self?
If you want ice pearl?
If you want the passion pearl in the background?

I paint out side so as long as the dry weather holds up I can paint.
The paint dries faster above70 degrees,  (taking less time to paint)  so I don't have problems with smearing wet paint. The clear coat is difficult it remains sticky for many hours (it needs to be 70 degrees or over) and outside something could get stuck in it.
