Take for example Collinite, Duragloss, or Zymol - companies like that - they probably sell 20, 30 cans a year based us yaking about stuff. (whaddia think ?) It may not be in their best interest, time-wise, to hang here. Then there`s companies that likely are in the same mindset as CarPro, where I recall, on here or AG, a rep specifically said that they want "the community" to sort stuff out themselves.
I can understand that a rep doesn`t want to get in the middle of a discussion about topping this sealant with that wax or whatever, when the end result might be a few units sold, when they can`t afford to keep up that momentum on other threads, and people are like "where`d he go?". They have to commit to it or just don`t do it. My 2c.
