I picked up my Pearl White 2 months back. I am thinking of getting Xpel on it. Usually, I have read on these forums that people get it right after delivery. My questions are as below: 1. Does it make sense to get it done after 2 months now? 2. Does Xpel give a new glow/shine to the car? 3. I read that once the Xpel starts coming out, the Pearl White for some reason starts to look a bit yellowish. Is that accurate?
