What brand of car care products are best??

[rmmagow]

I see you are in India so I don't know what you have available there. You might want to do what I did and go to a few car shows and talk to the exhibitors about what they use on there cars. Meguiar's here is supposed to be good stuff and I've used it to a high degree of satisfaction. There are countless options for this. I've seen wax products that cost $100's of dollars a tin which might be a bit much for a Volvo. The car shows are your best bet.
