Re: Meguiars Products any good ?
Meguiars is very good, I have used it for many years, their NXT waxes are very good.
There seems to be some confusion here by people who compare stuff like autoglym resin polish with what you are asking.
Mags make wax, completely different product to polish, polish is a cleaner, and autoglym resin polish has abrasives in it, you will see that it removes colour, thus thinning the paint or the clear coat.
Wax is a protector to seal and help prevent contaminants from getting into your paint.
The best way to get it all clean is to use your clay bar with the detailer spray as a lubricant, then a good coat of wax to seal it.
The clay bar is a safer way to remove the contamination than using any abrasive polish like AG, and AG contain petrolium distillitates, not good for you.
Wax like Megs and other good waxes contain "Carnauba Wax" as I sure you have seen on the bottles, the higher the content the better the wax, unfotunately you never get anything for nothing and "Carnauba" does not last forever but it will produce a great finish.
If You use a Megs wax the best idea is to give it a "Top Up" after washing the car every so often, use the "Fast Detailer Sparay" to boost up the finish.
Megs Carnuaba will last about 3 months in the UK, longer if you give it a top every month as I have already said.
Zymol is a pain in the rear because you are supposed to wet spray the car whilst applying it, and it is only made by "Turtlewax" as a up marketing ploy, the "Carnauba content is not very high and is over rated and over priced for what it is.
Your brother also correct "Mothers" is good similar prioducts to Megs it is just a matter of preference.
Another product that was originally made for boats is "Collinite" a wax now sold to the cars world.
If you really want to surprise your brother then tell him to buy "Swisswax" the price will kill him, beyond my budget for car cleaning but supposed to be the dogs bits.
