For any blasting project, we need your project clean and for us to have enough space to blast every nook & cranny. In order to do that, we need your project to be 100% accessible. How do you do that? Well it generally means removing any lights, mirrors, handles, or accessories from your project. It also includes covering up glass areas with thick cardboard and heavy duty tape (we recommend gorilla tape). To protect surrounding valuables, laying 4 mil. plastic sheeting on the object and/or on the ground protects the surrounding object from stray blast media and makes the mess easy to control and clean up (your preference).  If you plan on doing a lot of taping to prep your project, we strongly recommend that you clean your project first to allow the tape to stick better. Other than the plastic sheeting, the rest of the prep process is something we don't usually prep for residential customers due to liability concerns. However we can prep upon request.
