Autoglym
Autoglym products are generally intended to be used by hand although they can be applied by machine if you so wish. They are not aimed at the really high end detailing market, albeit they are better than their consumer reputation suggests.
Ultra Deep Shine requires a great deal of labour to remove: much more than SRP. I am not convinced by the finish at all. IMO it is not worht the effort compared to, say, Meguiar's NXT. However, the Workshop Manager at Aston Martin Works Service in Newport Pagnell (whom I recently had occasion to meet professionally) reckoned it was the best consumer product he had come across.
Cabriolet Hood Cleaner and Protector are both excellent.
Vinyl and Rubber Care is great, especially for tyres and other exterior black plastic trim. It leaves a lovely satin finish with very little sling and has surprisingly good durability (most of these products wash off in the first shower of rain, but AG VRC lasts a couple of weeks).
Interior Shampoo is very effective at removing grime from all interior surfaces. It does not leave any finish. It is quick and easy.
Engine and Machine Cleaner likewise is very effective in the engine compartment.
Intensive Tar Remover works, too.
Fast Glass is a brilliant glass spritz cleaner; Glass Polish works on more heavily soiled windows, removing waterspotting and aircon grime.
I have not used Clean Wheels on billet wheels. However, it works most effectively on painted alloys. It is not as good as Meguiar's Hot Rims, but significantly cheaper.
The metal polish works very well on under bonnet components, exhaust pipes, and chromed body adornments (radiator grilles and such like). It comes either in a tube or a bottle. The tube is easier to use.
I have been disappointed with the Leather Cleaner and Leather Care Cream. Does anybody make a leather cleaner that will get the grime out of my beige leather seats?
The best Autoglym product of all is Extra Gloss Protection. This is a paintwork sealant which should be applied over polished paintwork. It is a mix of natural (including Carnauba) and syntheric ingredients. Durability is amazing. I treat my cars to one or two coats of EGP twice a year (once in the spring, once in the autumn). My cars are often stored outside and are used throughout the winter. Yet the paintwork remains incredibly glossy and deep and water continues to bead. I'd say EGP, applied properly, lasts over 6 months or 10,000 miles. All the car really requires is washing. There is nothing like this product.
