I second Dusty's instructions; I have a touch up kit of paint and clear coat from Color-rite for my FJR. Pretty easy to use. What did you use to take decals off that make you worry about rust? Dusty, we seem to be agreeing a lot lately. Has the world gone mad?
How much of an area are you wanting done? I can do it for you cheaper than you can buy the materials probably. Unless you want a gallon of clear and activator. Most of the time 1 cup will cover 3 coats on your whole bike... Pay me for the time and I can help.
