Massive thanks to @shadow118 for his feedback and help! The skin is now finally at the level it should be.
-redone all Repsol and Movistar logos, mo more blurry mess
-added reflection map, the car now has a semi-gloss finish with matte decals
-changed number from #009 to #9. What was I thinking with that one?
I have now redone the skin almost completely, there is very little left of the original.
