Well you shouldn't have bought this.It's a cleaner polish and it would be abrasive to the paint work.You should have bought Turtle Hard Shell that is just a Wax non-abrasive.Just my 2 cents. I am not expert in detailing section though so let the expert's jump in.
I just bought it for a change but have an option to return it.So if u have any other option I would love to go for it.
Buy Turtle Super Hard Shell Paste Wax. It's good in low/mid range. Better than Formula and cosmic.BTW if the pain is dull or have some swirls then you can use this first and then apply the wax for protection.
Kangaroo is also good. Korean brand
Well i only know about Formula, Cosmic, 7CF, Turtle, Meguilars, Chemical guy's, Nano skin, Mothers, Sonax.Kangroo also fall's in category of Formula and cosmic i guess.
Yes price is 425 whereas turtle price is 510
I bought cosmic now
