Hi,
Im jut about to skinning some part from my motorcycle, my cuestion is that I can apply some stickers before the final coat, like the Ducati and some lines.
This is a great place, congrats for the great job that you're doing.

You will not have a good time trying to get the profinish into this contours. The backcoating reduces fraying, and eliminates unwanted fibre movement, but at the same time almost fully blocks the drapability. Where the regular carbon behaves like a cloth, profinish behaves more like paper. You could perform it with a heatgun, but I don't see that working well with either skinning or wet lamination techniques.
Jas1712: I really don't  see why profinish should have improved the result. I don't really see any misalignment or loose fibres. If you are talking about a v-configuration, the racing stripe would have covered the joint anyways.
