Testor's paint works fine. The tricky part is matching colors. I am a painter as a hobby/avocation, and mixing paints to match a color is a trial-and-error process. Sometimes you get lucky and get a great match right out of the bottle, but it usually isn't so simple. I have a Ritchey cross bike that is a sort of Molteni orange, and matching that color is very difficult. I have not succeeded yet in mixing an orange that matches the color of that bike, although my touchups look fine from a few feet away.
