The blue rendering you did is my fav, it reminds me of a blue Mach 1.
Don't do it unless your paint is complete garbage
As soon as the plastidip chips and rips you jave to redo the entire section in order for it to look good
So they sell you a product that you can already buy at home depot.
I know plastdip. That pos gp in my avatar was plastidipped. Im telling you that a touch up can be done but it's not easy. And if you go too thin anywhere it will be harder than Hell to remove
