I've looked for this in a few car parts stores around town, no luck so far, and found nothing on line. Where did you guys get yours?
You should be able to get genuine Toyota touch up paint from your dealer. You can also get aftermarket touch up paint from a bunch of places. I got mine in Magnetic Gray (the color match was perfect) and the Clear Coat from here: Select The Year The Tideland Pearl color code is 6S9.
