A sensor kit is provided to be used with a spray gun. The sensor kit may acquire relevant data while the spray gun is being used, and provide feedback to the user of the spray gun on particular parameters of the spray job such that the user in real-time can adjust his method of spraying. Furthermore, the feedback may be adjusted for different types of coatings using pre-determined data related to a specific coating. Even further, the obtained data during spraying may be sent to a remote server where data may be collected of a plurality of spray jobs using a particular type of coating. Using the obtained data during spraying, it may be possible to reconstruct what the applied coating looks like, and/or what the surface looked like on which the coating has been applied.
