I created the #3 BMW Williams of Juan Pablo Montoya and #4 BMW Williams of Ralf Schumacher for the Ferrari F2004 from scratch.
There are two versions of this skin, 2k and 4k.
I also made these F1 skins:
Friends also made these ones for you:
Jordan F1 (Niko Pennanen)
BAR Honda (Bontkraag)

Have fun with it, i hope you enjoy my work
