I’ve used mainly Auto Glym over the years. Been through the majority of their products.
Currently I use the following from AG
Shampoo Conditioner
Window Polish
Super Resin Polish
Bumper & Trim gel
Vinyl & Rubber care
Tyre gel (Meguiars is better)
The other products I have started using mainly through testing and seeing that they actually work well.
Bilt Hamber Auto Foam. — Doesn’t produce a thick “stuck on” foam but it actually removes dirt and grime. Unlike some others (Gtechniq for example) that go on thick, stay for a while then just leave the dirt behind.
ProKleen Trolls Breath - Contaminant / Iron remover. Does the same as other ones, turns metal red, strips nasty bits off the car and smells just as rank as the others costing 2-3 times as much.
ValetPro Bilberry Wheel Cleaner - Can dilute down to 1/10 and does the trick. Smells pretty good too.... but wouldn’t drink it. Not acid based so doesn’t dissolve wheels or fingers.
ValetPro Citrus Pre Wash. Can dilute based on dirtiness..... of the car. Can also be used on interior (high dilution) Very good at taking dirt off a car and leaving the wax on it.
Collinite 845 Insulator Wax - Best wax I’ve used. Needs a good shake to get it flowing but once it gets moving it goes on very easily. Give it 5 minutes to flash and buff it off. Excellent water beading for a few months and an even better gloss look. After this going on a BH snowfoam and rinse cleans the paint.
