Undercoating guns with extension hoses?

[b5blue]

  I'm looking for a setup to spray inside my hood, between the top and frame. Other areas also, not certain what I'm gonna use to coat or spray with possibly Eastwood's Rust Encapsulator or Rust Bullet. (I've got a good supply of Encapsulator on hand.)
  Eastwood has a gun W hoses for 65.00 and I've heard NAPA has a decent one also but can't locate one online. Ideas or recommendations?

Yes I was looking at that, and a gun and cup for about 60 bucks with shipping.  Or the Eastwood setup? (At least with Eastwood if it sucked they would refund my money!    )
