Not wanting to tread on toes but IMO both Autoglym super resin and Meguiars scratch x aren't all that flash. Yes they will give a great looking, glossy finish and look like they've removed some marks but, both contain fillers which will hide rather than correct any slight blemishes and after a few washed most will return. In my experience Autoglym on its own will last 2mths tops.
The products I've mentioned won't remove any significant marks either as they're more designed for protection, but the protection will be far superior to the others.
