Remove and paint stripes

I would not use Krylon or any other paint in a rattle can. These tend to fade pretty rapidly, and after all of the work you'll be putting into it, you'll be disappointed . Instead, go to an automotive paint supplier and get some one-part automotive paint. You can get a low-end HPLV paint sprayer (Husky brand from Home Depot are very good - they have a kit with both HPLV and standard guns for about 70.00 that is excellent.) and, if you don't have a compressor that will put out enough air, just rent one for an afternoon. Use the HPLV gun and make sure the airflow is sufficient for the spraygun - that's critical. You'll pay a little more taking this route compared to rattle cans, but the spraying is much easier, the finish is way better, and you won't see any fading for years. Also, the automotive paint tends to adhere better. The prep (removing the old decals, cleaning the surface and so forth us the same for either paint you chose.
