The sprays usually give you a nice even coat, unfortunetly for me it always tends to be slightly windy here so I always get a light layer of that crap on my side panels. Even when it's not too windy it still happens.

Use the tire swipes, they don't work perfectly but you will get a more even coat.

I've also started using Vinylex for the tires the past few months. A little goes a long way and it also gives a more natural look.
