First, these are definitely not the same product, but more importantly, each company’s selling approach is completely different. Liquid Ceramic® is a product sold online with no pressure salesperson involved. Rhino Shield is sold through in-home presentations by appointment only with their sales rep and can sometimes last 2-3 hours.
Second, Liquid Ceramic posts a cell phone number at the top of its website and you can call or text quick questions which will be answered even during off-hours and weekends.
