If the car is brand new..your saying it's an '07 or '08 model ...correct? The '07 Stangs stopped shipping in a few weeks ago.And being that it is new....when the vehicles come off the transport,they get inspected and thoroughly tested before being put on the sales lot.When the vehicle is sold,it is sent over to clean up aka detail.They wash and claybar the vehicle and I have seen the finish after they do this so I know it's been done.I get the cars before they go to detail.A lot of times they look like crap.
What I'm saying here is you shouldn't need to clay the paint.Wash it and then after it's dry,take the tips of your fingers and lightly brush against the paint surface.Does it feel smooth like glass or does it only sort of feel smooth with some grittiness to it like it feels as if it were still dirty?If it feels gritty in any way then you should clay it.Otherwise don't bother.Tungsten is a difficult color to spot imperfections with the naked eye.Try doing all of this in one of those do-it-yourself carwash bays.The florescent (spelling) lighting is one of the best to view your finish detail.Long as it's bright.
I didn't have very good luck with Zymol.And it only lasted a week or so.I used to think Meguires Gold Class was good for a little while.But it just tended to have more of an oily gloss appearance to it.It looked good then I noticed the Gold Class has some rubbing compound agents in it.If you use it enough,you will remove paint.And the NXT stuff is just a waste of money.I havn't tried Zaino myself but I know for a fact it's good.Check Consumer Reports ratings on Waxes and polishes by the way.You'll see there's more talk from the manufacture of these products than the results they actually bring...which is..most are no better than some turtle wax and black magic products.
You've actually seen a dealership clay a car? I used to work as a porter at a car lot (granted it was a LONG time ago) and there was no way they would clay a car, and that was the biggest and busiest car lot in Arkansas (Landers). I bought my old 05.5 Audi new and watched them detail and after that, my current 07 GT new and watched them do that one as well to make sure no harsh brushes were used on the paint and clay was never used, nor would I have wanted them to do it. I'm not saying your lot didn't clay, but I have NEVER heard of a dealership claying a car, it's just to long of a process for them to clay every car that gets sold and ran through detail.
Just because a car is new, I can almost garuantee that it still needs clayed. It probably collected rail dust as well as all kinds of airborne contaminates during transportation.
Also, are you saying if you use Gold Class "wax" enough it will remove paint? Sorry, but
There might be a very small amount of "rubbing compound agents" in it, but I would bet anything that no matter how much you use it, it will not remove paint. Do you think Megs, who is one of the most well known car care products manufacturers, would make something that is supposed to protect your paint that actually removes paint? For some reason, I'm doubting it.
Sure, you don't have to clay or polish and you can slap on some Turtle Wax and be done, but you aren't going to get NEAR the results unless you do it right and prep the car properly beforehand.
Oh yeah, I don't care what consumer reports says, Turtle Wax, in my opinion, is not near up to par as some of the other waxes and sealents out there, and yes, I've actually tried it a while back before I really researched how to properly detail and read about some of the other millions of products available. There are tons of better products and if that's all you are using, you are missing out big time.
To the original poster, I would try several different types of waxes and sealents and see what you like best. Megs NXT is over the counter and works "decently". It goes on fairly easily, but doesn't last very long in my opinion. Opti-Seal is online order only and relatively expensive, but goes on extremly easy and lasts a long time, but gives a mirror like shine rather than a true depth.
It all depends on what you are looking for, depth or shine. Try a few out there and see what you like the best.
