Ideally I would like some sort of grinding process that takes the blue paint off, leaving a base of factory undercoat that I can then recoat with chipguard and then repaint in its new colour (Signal Orange).
Thanks in advance,

Sounds like you're a gluttin for punishment with what you want to do.
Based on the above, and considering the car is a later model with o real damage to the original undercoat. I would recommend that you first heavily clean with a solvent, heavy nylon bristle brush that will get in the nooks and crannies.. then pressure wash. Once dry, scuff the surface down with a red scuff pad and some prep-sol. After which I'd scuff again with red pad and denatured alcohol and rinse with the pressure washer. Your now ready to coat with a sealer, or paint.. single stage enamel is what I like for the bottom. If you use the sealer you don't have to heavily coat it.. I like to just mist it on, and give it a light scuff before paint.
If you want to remove factory undercoating.. use heat and a scraper, if done right it'll roll right off. Then you follow-up with the wire wheels etc.. to get the small places you missed.
