FAQ from dipyourcar.com says
- How long does PlastiDip last? PlastiDip will last a very long time. We always suggest a minimum of 4-5 coats. We've seen wheels, grilles, ect dipped for over 1 a year without having to be touched up. Unless there is a specific event that damages the PlastiDip, it will hold up great and keep it's finish. It is very durable and will not lose it's bond.
- Will it hold up to the elements (sun, winter)? PlastiDip is extremely resistant to the elements, including sun fading, winter ice, cold, salt ect. A lot of customers actually dip their wheels and cars specifically to protect the original surfaces from the winter season.
