NO. Dont do it. Especially white. Here is a quick time line of my plastic dip experience.
Right when it was done:
Looked great, right? Oh, it did and I was VERY happy with it. Two months later...
When I sold it 9 months after being painted:
Rubber stains... you touch the car with your dirty fingers and it would not come clean. Scrub it too hard and it starts to peel. Cleaning would resort to spraying over it, but that area would be more white than others. Dirt/bugs on the front, rust under the OEM silver paint on the hood started showing through (but wasnt on the silver paint... it was weird), I will admit the damage/hole is my doing, and if a bird shat on the car... don't get me started.
Spray it on too thin, and it flakes off. There is a reason the dipyourcar.com videos never do the roof of a car... water tends to sit on the top of the car and make the dip disgusting looking. Paint started flaking and peeling on the roof within 4 months. I have black plasti-dipped things and noticed the black lays down much thicker, so you will need more of the white. I had 3 gallons from the company, and I wish I had another gallon at least.
Small things, P-dip is good for... not an entire car though. these are just my experiences and I might have been OCD with the car, but it was my second biggest regret I had when owning the car.
