Coastal Shield is Sussex County’s trusted name in ceramic coatings and auto detailing. Formerly known as Bavaria Mobile Autowasche, we recently relocated to Lewes, Delaware to better serve our growing base of residential and vehicle clients across Rehoboth Beach, Bethany Beach, Georgetown, Milton, and surrounding areas.
At Coastal Shield, our mission is simple: deliver premium ceramic and graphene coating and detailing services that protect and elevate your most valuable investments — from luxury appliances and designer kitchens to exotic cars and marine vessels. Whether it’s your home, your vehicle, or both, we treat every surface with the same level of care and precision as if it were our own.
We offer expert ceramic protection for home interiors including stainless steel appliances, wood cabinetry, leather furnishings, glass, countertops, bathroom fixtures, and more. For vehicles, we apply graphene and ceramic coatings that keep exteriors glossy, clean, and protected against UV damage, swirl marks, and road grime — especially important in the coastal Delaware climate.
Our Story
Bavaria Mobile Autowasche was founded in 2020 by John Stonemetz, a lifelong car enthusiast with more than 30 years of hands-on detailing experience. With a professional background working with luxury brands like Mercedes-Benz, Volvo, Volkswagen, and BMW, John built the company on a simple belief: “Obsess over the details, or don’t do it at all.”
During the early days of the COVID-19 pandemic, John saw an opportunity to turn his passion into a business. What started as a mobile detailing service quickly grew into a thriving ceramic coating and protection company with a reputation for excellence across Sussex County.
Homeowners and Car Lovers Trust Coastal Shield
What sets Coastal Shield apart is our combination of technical skill, unmatched product quality, and personal service. We’re not a one-size-fits-all shop. Every home surface or vehicle gets a tailored protection plan based on how you use it, what kind of wear it sees, and your long-term goals. We take time to explain the benefits of each coating, what to expect, and how to maintain it for maximum results.
Clients come to us because they want peace of mind. They want to know their Wolf range won’t scratch from daily use, their Sub-Zero fridge will keep its sheen, and their Porsche or Tesla will keep turning heads. They stay with us because we overdeliver — with real results and service that feels personal.
