Agreed, I did the same thing and it is very easy once you get the hang of it. A variable temp heat gun does help.In my opinion, the best option is to wrap your interior pieces. It is very easy to do, and there are a plethora of YouTube videos explaining the process. I personally have used vvivid and 3m vinyl. I prefer the vivid for their carbon fiber, 3m for their solid colors.
The best part is if you don't like it, you peel it off with no harm done to your interior piece!
It's pretty cheap, easy to apply, and lasts for 3 to 5 years. Possibly 7 to 10 if cared for right, and applied right.
