Hi Silver...first and foremost, welcome to Autopia :welcome
In regards to your question, paint prep contributes 90% of the paint's overall gleam with your last step product (LSP) contributing the rest...so definitely do not skip out on the prep. Although you can get nice results by hand, the best results are achieved by machine when it comes to mechanical polishing. I would recommend the following for polishing/glazing:
1. Menzerna polishes (Intensive Polish and Final Polish II) - I have sampled several polishes but I always come back to these twins. A close second goes to Optimum Polish (extremely versatile product that has nice defective removal range.
In regards to LSP products I would recommend this for your car:
1. Klasse Sealant Glaze (SG) - the name is very confusing in that it's not really a glaze but an LSP. You can layer several times to improve both looks and durability (I recommend 2 or 3). The look is very "glass-like" in that it makes my clear coat look several inches thick. Application can be tricky - apply extremely thin (almost that you cannot see it) or it will be difficult to remove. I personally always top SG with a carnauba wax --> which leads me to my second choice.
2. Pinnacle Paste Glaz (PG) - Unfortunately this product has been discontinued, but a few members here might be willing to part with some for the right price. Honestly, durability is only decent, but this wax is all about enhancing the beauty of light-colored cars. As I alluded to earlier, put 2 to 3 layers of SG on your car then top with PG and you get the best of both worlds.
3. Four Star Ultimate Paint Protection (UPP) - Another option that goes really well with silver. Polish and go straight to UPP. Leaves the surface extremely slick and with a liquid glow. I may be in the minority here, but I do not get more than 2 months of protection...but this is one of the easiest LSP to apply and remove so you could throw another layer on really quick and not have to worry about durability.
In regards to car wash, I really like Meg's Gold Class or NXT shampoos - They are available everywhere and are extremely cost effective. For online shampoos, I just received Chemical Guys Maxi Suds (
Danase) and was really blown away...definitely my favorite. Key things are to focus on your actual washing and drying technique, soap is not going to save you if you have poor wahsing/drying habits.
For tire shine, I really like Mothers FX Tire Shine. Easy application and pretty good durability for a water-based product.
Sorry for the long post, but welcome to Autopia.
