Slow down now! I don't feel confident enough for that yet! My brother-in-law has been trying to put a tattoo gun in my hands for years. I finally took the plunge when he wanted me to do a cover-up, stating that I couldn't make it look any worse. It's a hard thing to get comfortable with when you know you can't fix a mistake.
On a paint job, I know that no matter how bad I "F" something up, I can always fix it. This is different. Maybe that's why it has a different sense of pride and reward when you get it right - and you didn't screw it up!
