Walt,

I had clear bra installed on my new Gallardo. It came with a can of Plexus and I have used it with great success. It not only polishes it, but it selas it and actually penetrates the plastic material. It conditions it and provides protection against yellowing and streaking. The clear came with an instuction card and it says to use the Plexus at least twice a month and everytime you wash the car. I will use it weekly. My clear bra is almost completely undetectable and shines with the same vibrance of the paint.
