Re: Brand New! Already damaged.
As luck would have it I am the tube repair guy at Bennington, sorry to hear about your boat.
I am afraid you are gonna have to get used to it, you can get the scratch out but not the dent, that involves drilling holes and a dent puller and welding and even for me with 23 years experience I can only pull that off about 50% of the time and have it look good, normally you end up with 20 small dents instead of one big one.
You can try to sand out the scratch but you are likely just going to make it more noticable because that metal will never match the tube and even a small scratch makes a repair area aboput 6'' in diameter and involves 2-3 grits of sand paper, a Scotch Brite pad and rubbing compound, not something you want to do for the first time, I gaurantee it will look worse than the scratch does now.
The problem is the metal is so thick you just can't get a small dent out like you can with a car fender, then again you can dent a fender with your thumb but not a tube.
Wait a couple weeks and you won't notice it, that is really the best I can tell you and somone may tell you fill the tube with air and pop it out but unless you have some really smart air that won't work either as the air pushes evenly on the entire tube and too much air will get you looking like the sticky at the top of this forum.
