Swirls in Clear Bra

[vosstire]

I have a customer who brought her vehicle to me with swirl marks over the entire hood and quite visible under the clear bra installed on her hood.

I removed the swirl marks from the hood but she insisted the swirl marks under the clear bra were actually on the clear bra surface. Furthermore she demanded I polish the clear bra, which I declined since I was using Meguiar's M-80.

She returned a couple of weeks later saying she had taken her vehicle to a detailer her removed the swirl marks from the surface of her clear bra.

3M does state their paint protection film does contain a clear coat, so is it possible to have swirl marks in clear bra and is it possible to buff them out with a polish such as M-80?

I polish and wax the clear bra on my M3 just like any other part of the car. Seems to work fine.
