Not in Washington but I looked up a guy in the yellow pages who works out of his truck.
He came by, I looked at the job on his truck and had him do mine. Almost a year later and it still looks perfect, no bubbles, discoloration, etc.
I think I knew it was going to be fine as a result of what his ride looked like. It was obvious that he used first rate materials and knew how to apply them.
Just a thought.
