Apparatus and methods are disclosed to provide a guide for sand blasting a fiber-reinforced object. The proposed guide consist of three-dimensional (3D) features that will result in reflective ray-like protrusions that can be detected and displayed by Augmented Reality (AR) hardware including a head mounted display. The AR hardware determines a virtual object to be presented in a field of view, a position in the field of view, and a perspective of the virtual object in the field of view based on position information from the reflective ray-like protrusions. At least a portion of the sand blasting area is observable through the display and lens when the display is presenting the rendered virtual object.
