Just got myself a 3 year old Multispace. OK, OK it does what it says on the can for me. Can anyone recommend a top quality coloured scratch cover type stuff as it has various scratches. I want to touch up and would rather not use touch up paints unless I have to. Alternatively is there any other method used by the experts I should know about.

There's a few polishes that claim to cover scratches, but I've found them rather poor. Also if you do use touch up paint (great for just covering them) make sure you get the right colour.. Twice now I've got the non-metallic version and wondered for ages why it looks similar but not quite right

Steer clear of any kind of touch up paint unless you are 100% sure what you are doing and only ever use them for chips or areas where the paint has been completely rubbed off.

For fine scratches coloured polishes work pretty well provided the polish is a reasonable match for the paint, the range of colours is limited so don't expect too much if you get a poor match. They are very good indeed for hiding car wash swirl scratches.

door edge chips and deep scratches can be hidden to some extent using the coloured wax crayon supplied with some coloured waxes.
The procedure is use a rubbing compound (T cut do coloured ones) then wax with the coloured wax. Wear gloves use the 3 cloth method, one to apply, one to remove most of the wax and one to buff the wax.

The coloured waxes don't give a really deep shine but you can go over the top with a normal deep shine wax such as normal Turtle Wax.
