Hi all,

I'm a bit worried about sanding too far because I haven't done any carbon work before. I'm not sure how far down the de-lamination has occurred, in one spot it almost looks like its between the weave. 

Theres a very significant change on the surface when you hit the carbon. It's like the light hits the carbon strands differently, You will know when youve sanded enough. It doesnt matter if you sand into it, but you can sand through it if you just plow through it. The surface layer is at least .25mm thick, if you sand through it, youll see the weave from the layer below it and it will look naff. Use 300-400 grit to get most of the lacquer off, then move onto 600-800 to get the last bits.
