I can do it for you but I guarantee you I would have to “Re-prep” the car. Not that I don’t trust your handy work but it is never as easy as clean, mask, and spray. Also, I would rather get the materials so I can be sure I’m using good stuff. I can’t tell you I will be the cheapest but I can tell you that you will like it.
You said it is not going to be perfect. I disagree.
Let me know.
