I would go with a clay bar, aggressive then fine, and lots of soapy water, glide of you like and see what it does. I've done this with sucess but only once

The 3M eraser is also a great tool as it is a friction not a abrasive, meaning it may take the stripe but it won't damage the clear. It may not be aggressive enough like the clay bar. I've used a lot on tape and principles say it works for paint applied over clearcoats

Then your into chemicals, either easy off, acetone, or thinner and lots of washing. You don't want to be aggressive as the clear will give a little along with the typical striping paint. Easy does it. You will have to hand polish, glaze, and wax no matter what you do even clay bar. but it will be minimal.

If the stripes are chemically bonded to the clear you will be color sanding and polishing. not only to remove but to level the paint.

It all depends on the paint and the prep. It there a name on the design? is that all the pin striping there was?
