I am using P21S wax for the first time and I am absolutely amazed by the shine. I have been a huge fan of Zaino for years but now that I have tried this product, I will get off my lazy ass and detail more often since it doesn't last as long as Zaino but instead I will get this incredible shine and depth on Jet Black!! :eek:

Only question is, how do you know its time to buff it? I run a 12" by 12" area, do I buff right away, wait 2 -5 mins? whats the deal here? I am getting good results now but I want to maximize it.

Also, how many coats can I put on? do I need some wait time in between?

I believe most carnauba users wait for the solvent carrier to flash off (haze) before buffing.

I wouldn't think carnauba waxes could be layered the same way sealants can be. It would seem that the carrier solvent for the wax would partially dissolve the layer already on the car.

As I understand it, P21S buffs off quite easily. Just to be sure, I'd go ahead and do the whole care and start buffing where I started to make sure it's had time to haze.

You can't do that will all carnauba waxes though. Collinite 426 works a little better with the wipe on, wipe off method. If you do the whole car with 426 and then try to buff it, it will have hardened to the point that it will be difficult to remove. I won't make that mistake again on the Grand Caravan. :)

I haven't used P21s, but I have used S100. The instructions on the S100 jar specifically say that you should remove the wax before it dries.

So check the P21S jar for specific instructions. My guess is that they will tell you to remove the wax before it dries, too.

I just got that wax as well and am amazed with the results. Great stuff and a lot cheaper than Zymol concourse:D. I usually do a section such as a quarter panel, and then by the time I apply the entire quarter panel, I go back and start removing once Im finished. The directions pretty much say you dont have to leave it on for any length of time, but its great stuff, highly recommend it. Most importantly make sure the paint is cool, or it creates a big mess.

Why pay $35.00 for P21S when S100 is at $15.00?

S100 is like putting hot butter on the car and yes, follow the directions.

If your car looks awesome, it's due to the fact that the paint is clean and shined, wax has nothing to do here. In other words, great wax on weak paint is weak, good wax on great paint is great. It's all about the prep work. S100 FTW if you are into carnauba.

I just S100'd my car last night. I only leave it on for like a minute and then give it a good buff. Do not let it dry. The shine is amazing, I do however wish it lasted a bit longer. I may just be greedy.

Curious... does the P21S jar say to not let it dry?

I think the S100 says that to keep dusting down. Dust is a big annoyance for most bike guys, so if you don't let it haze it won't dust much. I've always applied it to the entire car before wiping it off.

i would advise doing sections at a time, regardless of the actual product.

Why? I don't see any reason.

I have a container of both S100 and P21s, and the directions for use are identical, as both say, 'For best results do not wait for wax to fully haze over'..

I have a strong tendency to follow directions. :)

Because it becomes really difficult to remove it. The section at a time method, I find makes it very easy to remove it, and not miss any spots. When you miss a spot and go drive your car in the sun, it become a real bitch to get it off. You have to break out the clay bar to get it off.

Which wax do you find better of the two?

Ive used S100 for years with great satisfaction, but I was tired of reading conflicting claims about whether P21S is the same stuff at a higher pricepoint or not. So I finally broke down and bought a container of it... From a comparison of the appearance and the smell, I cant detect any difference. But I havent used it yet. I still have a tiny bit of my S100 left. I think what I might do is, the next time I have to wax, Ill split the roof in half, and treat one side with S100 and the other side with the P21S, and compare their relative appearance, and their relative longevity before water stops beading. Ill report back here once Ive done it.

Wow. I'd always heard it was really easy to remove even after hazing. As in Zaino easy.

Oooo, nice. Can't wait to hear back on that.

Be sure to take some pics and cross post it over on Autopia.

P21S is great stuff. Best applied in a thin coat to clean, sealed and cool surface out of the sun. Go a section at a time with a microfiber applicator in a back and forth motion to prevent swirling if any contaminants get on the applicator or the car.

Remove the wax residue with a micro cloth "just before the wax hazes over and dries" the same way - back and forth in the direction of the airflow - as per the instructions (and stated above). 2-5 minutes seems like the right range depending on humidity, etc.

Layer an additional coat if you want, but wait 24 hours between applications. I've used both S100 and P21S. I side with all of those that say P21S has more carnauba, better reflective properties and greater longevity over S100.

:confused Never had that issue or thought it was hard to get off (in fact S100 is one of the easiest). Any time wax is in the sun it's a pain to get off, really has nothing to do with how long it was sitting on the car.

I don't think s100 is ever hard to remove, it is just 'harder' to remove after hazing over.
I don't do the whole car at one time because I can see little streaks where the wax dried(and this is in a garage). Might just depend on how fast you are, what the weather is like, and what color your car is. Oh and how anal you are.

Anal, yes. Fast, very. ;) Maybe that's why I don't see any issues from time. Definitely have seen issues from direct hot sunlight though.
