Why Trex Protect?

In our survey of deck builders, they told us that 98% of 8-10 year-old decks have splitting, rotting and decay. For the $8,000 to $10,000 price of the average deck, wouldn't it be wise to spend a few dollars to ensure the screws will hold longer and stronger, and the tops of the joists are protected from moisture?
