I got a carbon fiber tank of ebay, I believe it's 68/4500. Anyhow, it was born in 2002, and it was tested in 2007. It said it needs a new hydro in 2012. My question is do you think it will pass if I send it to get tested? Also there is no refund for failed tanks, correct?
Also, when we talk about damage, it really applies mostly to internal stuff. Sometimes, you'll find used carbon fiber Guerrilla or Ninja tanks with some cracking or peeling of the black outer coat. That shouldn't affect hydro testing.
