has anyone tried this?

ive used it to touch up some spots on my car worked pretty good....just gota use it lightly so it leaves no bubbles. Id recomend it. Make sure you git the right color tho lol.

Thats looks preatty nifty. However, I found that using factory touch up paint and allowing it to dry partially, then using a razor balde to scrape off excess to work well. Not only that, but it is faster and easier. You don't have to write up step by step instructions, unlike that stuff.
