Bob,
Management may have made a huge mistake in "redirecting" your talents. You have been an ambassador for ERA, and the selfless help you have given owners of other brands extends that to encompass the industy. You are a great engineer and a fountain of knowledge - each post is a gem.
FWIW, having Peter work on the cars could end up costing you more time - if you count the effort required for you to design an OSHA approved mustache guard.
