I played with the Subaru J# touch up paint before the weather got too cold.
1.) The color is close...but not spot on. I have ice silver. The touch up was certainly blue'er than the color on the car that has seen sunlight for about a year.
2.) The "precision tip" is a joke. It will not flow. If you can get some paint to flow, its pretty much too dry to work with. Just buy a few 00, or 000 paint brushes, and dip into the bottle.
3.) DO NOT use the abrasive tip to dress any marks. That tip has got to be made out of some sort of industrial diamond, made in a nuclear reactor. It is HARD!...and will destroy any small chips and make them worse. Use some rubbing compound instead.
4.) The clear coat part of the package is actually pretty easy to use and gives good results. The foam tip is a little sloppy. My wish to use some of those 00, 000 brushes with this too.
