@ahmadbila. Tnx a lot for your replies, comments. Well I used Formula one some six years ago on my previous grey Khyber. It was a good soft polish.
Cosmic I fetched form Metro Isl recently as you are confident about the originality of the product they are selling. I found it good today. Only on bumper I felt the static electricity when I applied this polish there, on metal the dust did not come so quickly.
I saw somewhere ant-static spray which I think must be effective in this situation. An idea came to my mind that we should get anti-static pad and put the cleaning rag over it, because the cleaning cloth also accumulates static charge.
@shirazkhan. Tnx for your nice comment.
