I believe i got them for 5500 and they were ready made. As i said they didnt perefectly fit with the contours of the seat, only fabric stitched into the seat will accomplish that can accomplish that.
As for waxes head on to car care detailing dreams thread and ask the question, you'll get a much better response by professionals.
And as far as i know you can get the waxes from Shahid Autos F-10 (besides Shell Petrol pump in main market), Dubaiautos isb in i8 markaz and dubai autos RWP as waleed80 has said.
I advise Shahid autos as it has got a more wider range of detailing products avalaible and they are at an reasonable price too.
