Back in the GMRoadster and Strictly Aftermarket ventures, Martin was splitting his duties between being an Executive Chef and running a car business. Neither venture faired well because of this.
With the advent of RPM, I have heard that Martin has given up the chef side to devote full time to the RPM business. I have heard good things from MOST of his customers, but there are still some that are disgruntled, but that is true of most businesses.
Personally, I have not done any business with him, so I cannot say one way or the other. If I have to do business with him, I'll be counting my fingers both before and after I shake hands with him.
