Stripe removal....

So Herbie could lay paint very well when he shot my Fury 13 years ago..... Don't know what he did different to the Shelby 5 years ago, but at the end of last year, it started to get a zillion little bumps that look like tiny pimples all over the roof, hood, bed rails and even the plastic light bar. Needless to say, it has progressed rapidly and my nown next project is sipping it down, prepping and doing my own paint since we did OK on Jake's 02 Ram last summer. So my question is, what is the best method for stripping the decals/stripes off the thing?

I have the same thing on the top of my white intrepid. I was told the primer/sealer undercoat was not allowed sufficient time for the solvents to totally flash off before color coat was applied, so the solvents are sealed in and are drawn out by the sun especially on the horizontal surfaces.
