It's not a cost thing to be honest, I'm just thinking paint will have better longevity. Removing the trim then painting the V on the back of the car doesn't seem that difficult to me. I'll probably do the paint or wrap myself regardless, I'm pretty handy. I just want to do it once and not have to do it again. I've heard rumors that paint doesn't stick well to this trim for whatever reason but haven't actually seen any painted trim jobs in person or long term reviews on how paint holds up on it.
