    Wait, what? It seems like you just asked how to remove paint without damaging the paint.

    I'm trying to remove enamel touch up paint from a frame without ruining the finish underneath. This is paint that has been added on top of the clear coat that is already there.

    Anything you use that will remove the touch up paint (solvent, abrasive etc) will also affect the paint underneath.

    If you really can't live with the touch up paint being there the best way to remove it is with carfeul masking, careful sanding and then applying new matching paint and/or clear coat over the area you have sanded.

    Carbon fibre is much harder than most paint finishes so as long as you don't go crazy the risk of damaging the frame is quite low.

    Epoxy used in CF composites and two part catalyzed epoxy or polyurethane paints are resistant to most solvents like acetone, lacquer thinner, etc.. Enamels are not and quickly dissolve with the these solvents. To resist oils, greases and other common fluids used on bikes, almost all paint used in the commercial production of bikes is the two-part variety. Test in an inconspicuous place.

    There are chemicals that can soften/remove two-part paints. Methylene chloride is one such chemical used in paint remover. This will attack CF composites, but can be used to remove paint from CF by minimizing the time and exposure of the underlying CF.
    Do the math.

    Thanks guys.

    I figured a light sanding was probably going to be my best option. I have clearcoat I can put over it afterwards. I'll give it a try sometime this week.

    I'll test some acetone under the downtube by the BB since no one will ever see it. If it doesn't destroy the finish i'll use it to remove the paint and then do a light sand / clearcoat and polish.

    Thanks for the feedback.

    I'd just put a cool sticker over the problem area and forget about it.
    Safe riding,
