I bought Avery Gloss Black for the wrap and the tools to make it easy. My girl and I also used a heatgun. Helps a lot especially the bottom (back part of it) portion of the spoiler. It took awhile, and lots and lots of patience. What’s good about this type of wrap I bought is I heard it’s very beginner friendly and doesn’t rip off easily as others. There’s videos out on YouTube that shows you how to wrap a spoiler but my girl and I just kinda winged it and tbh it turned out better than we expected and it was our first time. Don’t expect it to be perfect, and you’ll do just fine:). Good luck! 🍀
Edit: I’d also suggest investing in knifeless tape if you don’t want to accidentally scratch off the paint while using an exacto knife. You can find one on Amazon as well! :)
