Never liked the stuff. I know that a person who ownes a Vette would like to make some nice appearing changes under a dull hood, but this is where you shouldn`t start. Your eyes are drawn to the hoses and most of the time they have kinks along the hoses. The first place a Judge will look and possibly mark down an otherwise nice piece overlooking some other nice appearance changes. And apparently you have some reservations about them also. Put the stock hoses back on.
PS.

No offense intended, but a better job for you would be to remove the possibly overlooked rusty hood hinges and repaint them. Overall, the car looks very nice.
