I have now driven my car around my neighborhood as well as another near by. Waiting anxiously for my title and Plates so I can hit the Highway. I understood the pinging from road stones, gravel, etc., while in cart stage with all the exposed aluminum. But, now that I've undercoated the entire body, rear splash guards and entire rear wheel wells, the pinging hasn't abated. I will tackle the front splash guards next but, will I need to undercoat the entire underneath, including the beautiful powdercoated panels?

Advise would be appreciated.
