ive used sika-flex (they use this in body kit shops aswell) before, its really strong and durable for the exterior. though im not sure if you'd want to stick the rear diffuser on it would be pretty damn hard to remove,but maybe you can use screws and double sided tape? but if you wanted to try sika-flex you can get it from your local bunnings.
ultrex has quiet a selection of grills, lips and other cosmetic add-ons browse the site, I'm sure you'll be able to find something that you like.
