Hi,
We finally finished our BMW 3-series interior in carbon. We followed step by step the tutorial but we have in thing really strange.
Left door handle is super shiny extreme deep gloss, near-perfect gloss but the right one is not so gloss, not matte but I don't have that super shiny effect. The piece looks a bit blury and we restarted the sanding process 2 times and the first time wasn't correct enough. (From 400, 800, 1200 + polish).

We have done the same process for both piece.
What can it be ? I need you advice.
Thanks,
Lionel

I suspect you have moved up to a finer grit too soon or you have got a bit of grit in your paper.  Zoomed in you can see a lot of scratches on the surface. The solution is to go back down the grits until you can remove the scratches then work back up to 1200-1500 and then polish again.  Hopefully that should solve the problem.
