4 Star or atleast Premium Auto Care was purchased by the folks from Autopia a year and a half or two years
ago. It was at that time David B. was able to begin making his own products under the 4* roof... the Four Star line has the Ultimate line along with a Professional line, and now the Ultima line produced by David B. Just like Meguiar's it has different products for different consumers. 4 Star Ultimate line is a great line at a great price ... no need for Ultima, for me atleast.
