If you want basic affordable cleaning and care without busting the bank, look into getting the following:
> Turtle Wax car shampoo
> Jumbo sponge
> Rectangular bucket (afterall, the sponge isn't round)
> Autoglym Super Resin Polish (red label)
> Meguairs Cleaner Wax
> Chamois leather
> Silicon water blade
There are more products you can get depending on how far you want to take it but for basic care, a wax like the megs is a good start. Super Resin Polish is a good way to get a shine and remove some very light scratches but I'm not overly keen on the white residue so prefer the cleaner wax (depends on how much time I have).
Keep the cleaning up and that will be a huge boost for the longetivity of the paintwork. You don't have to wax/polish it every time, just once in a while will go a long way.
Something is better than nothing.
Different people will have different opinions and preferences. Its a case of finding products that
you like and can work with.
