With every spray painted job Paintworks supplies a free touch up kit. Ideally you won’t need this, and fitting your job will go without a hitch. However, accidents do happen!
If you scratch the face of a door, you probably won’t be able to use the touch up paint to make an acceptable repair, and in this case re-spraying will probably be the only option. But if you chip a corner, or slightly damage an edge, a small touch up might just solve your problem.
