Your civic looks amazing MashAllah. I so wanted to see how maxwax would look on a silver since I've heard Ahmad bhai mention it in the recommendations. It surely looks great MashAllah and somehow appears better than your last few details with different LSPs (not sure if its the pics or actually it looks better than the last few details).
Your mention of abrasive in the shampoo and discussion between @dude007 and @durrani_45 got me thinking a bit though.
Its a new information for me as well. Never heard of a car shampoo with abbrassives (basically putting a shampoo between your fingers and rubbing them and you could feel the particles and that effect also being transfered to the diluted solution made. Even if you can feel particular in its pure form, I am sure they dissolve in water. Shampoos are something thats always advertised to be safe for the wax, safe for clear coat and its strength is always indicated by extra mention of "concentrated" so people could dilute it accordingly as per the concentration they want to get the level of "cleaning" they are after. Also looking around on the internet e.g.
3M Car Wash Soap, 3m 39000
mentions the emphasis of it being very concentrated (yet still asks to pour an ounce into bucket which is what others do too). I have seen some shampoos e.g. in the FinishKare range that requires 1/2oz for a gallon.
The description of 3M shampoo say "100% safe for clear coats" .
I am sure it offers better cleaning though compared to other shampoos as per yours and durrani's practical experience.
