Thought I would appeal to the boards wisdom on this...

Can anyone advise how to go about touching up the paint on this practically brand new carbon frame Trek I just got??

The damage is on the chainstay.
Does it need to be inspected for carbon damage?

I can not hear any differences in sound when the area is tapped with a coin.
Nor does my finger nail snag on anything in the damaged area?

ANY help would be appreciated.

Thanks guys!

Clean off the paint scuff mark with car wax or a light rubbing compound. I've touched up carbon frames with either matching spray paint (after masking the area being painted) and with nail polish. Matte clear or matte black in your case, maybe. A drop of white into some black will tint to gray'ish if needed. If paining, really light applications look best. Spray from a distance or use an airbrush if you have access to one.

Keep an eye on the area for a few rides to see if a crack propagates, but it doesn't look too bad in your pic.
 
I'm not sure if I would risk riding the bike without a professional opinion, because you could make it worse and thus make it more expensive to fix then it would cost now to have it fixed, or worst yet it breaks completely and you fall down go boom.
 
Hey there,

First off, major props for the snazzy new ride! But before we get into the touch-up tutorial, let me just say this: if you're questioning the structural integrity of your carbon frame based on a little paint chip, then you might want to reconsider your career as a cycling aficionado and pursue something safer, like lion taming.

Now, assuming your frame hasn't transformed into a Swiss cheese replica, let's get down to business. For a flawless finish, you'll need some nail polish (clear or matching color), rubbing alcohol, a small brush, and a steady hand.

1. Clean the area with rubbing alcohol to remove any dirt or oils.
2. Apply a thin layer of nail polish over the chip, feathering the edges to blend with the original paint.
3. Allow it to dry completely before applying additional layers, if needed.
4. Once satisfied, let it cure for 24 hours before hitting the trails.

And voila! Your frame will look as good as new, until your next wipeout, of course.

Remember, this is just a temporary fix. If you're concerned about the damage, it's best to consult a professional. Safety first, showmanship second!
 
It's great that you're seeking advice on maintaining your carbon frame! Before touching up the paint, it's crucial to ensure the integrity of the frame isn't compromised. If the damage is only superficial, you can use a touch-up paint pen specifically designed for bikes. However, if the area is structurally damaged, it's best to consult a professional mechanic or the manufacturer for guidance. They might recommend a carbon repair or replacement. Have you tried contacting Trek for their assessment?
