Advice needed - carbon lacquer flaking on bike

Looking for bit of advice / reasurrance - cleaning my bike on Sunday I noticed what appears to be the varnish top layer flaking from the seatstay / chainstay. It looks like its where the rear dropout is fixed into the frame and then spreading upwards. :shock:

1) It looks cosmetic, in which case i'm not fussed and i'll seal it - advice what to use, some sort of varnish how best to prevent it spreading?
2) Should i be concerned as to the safety of the frame?

Have other people experienced something similar to this? BTW, its not been crashed or anything, just looks like a dodgy finish!

Hopefully the pics will help

    if your worried about it, just pop down to your local bike shop and ask them to have a look at it. its a bit hard to do it from pictures.

    Probably due to contamination under the paint - I'd take to your Pinarello dealer for a second opinion.

    Pah! Should have learnt about Italian workmanship from my Alpha Romeo owning days ! Any ideas what would be used to seal it?

    Some automotive aerosol clear lacquer will be fine - rub down the surface with very fine wet/dry, particularly to get to an area with firm adherence / no lifting. Wipe down surface to remove any grease / contaminants and then spray. I would do this indoors or wait until the temperature is warmer if spraying outside. Leave for a few days to harden-off if poss.
