I have a 2002 Gulfstream. I bought new decals to replace the faded ones on the cabin and provided them to my dealer to install.They were to remove the old ones and place the new ones. They also replaced the fuel line connector on my starboard Honda 130. I was charged for 6.5 hours of service time for a total of $643.00. Has anyone done these 2 jobs themselves? Should it take 6.5 hours? I was not too happy when I received the bill in the mail as an addition to my winterization invoice. Thanks for any help with this.
