I know the answer to this may seem clear cut but I wanted to check to see how I should best handle a question from another brand operating in the same marketplace with similar products. They have been in touch to ask about where we source some of our components to apply a particular finish to the goods we make, clearly because they want to begin applying the same sort of finish to their own. They have also asked us what equipment we use to do so. The obvious response is to not respond at all: why should we help a potential competitor. However, we often see this brand and other brands at various events, and we're all discussed by an active consumer base with blogs etc, and we don't want to create any hostility or difficulties. We don't want to be perceived as unfriendly, mean, or to have our reputation tarnished etc. How is best to reply in that case?
