Wow...$3300 for PPF seems like alot. You could have the whole exterior properly repainted for less than that.I had my 2 door wrapped in February, excluding top and fenders. I had quotes ranging from $2,425 to $5,500. I went with the below shop and film for $3,300.

From my research, the cost variances come from quality of film and extent of installation. The high end shops remove, fenders, top, emblems, etc and truly cover all painted surfaces and essentially hide every edge possible. The middle ground don't go that far, but only with a close look can you notice the edges.
I haven't had mine off road yet so can't speak to trail pin stripe protection. However, for everyday stuff like dirt, mud, bird droppings, etc, cleans up real easy
