Hi guys...

I purchased my brand new 8 last friday, but we got rain everyday since I got my 8.

Now my grey 8 has too many water marks.

I saw a thread that says Turtle products are pretty good and not expensive, so I bought turtle car shampoo and liquid wax.

But also some people said I shouldn't use any products for new car, b/c new cars got some kind of coating on it?

Anyone knows about this?

turtle products should work just fine. Car shampoo and liquid wax should be fine to use on new paint as long as you're not using a buffer and are just hand waxing.
Get some good microfiber wash mits and towels and you'll be fine.

Thanks Jedi... but what do you mean by using a buffer?

high speed buffers like the ones they use at car washes to remove / apply wax.

The paint is cured in a heat booth at the factory.

Full curing occurs within 3 months.

youll be fine just dont use anything extreme like dawn or hair shampoo....and try n do everything by hand, just give the car some love and youll do fine
