These are the three that I've closely scrutinized and have come to a short conclusion if you don't care to read on. Klasse, Zaino, Meguirs, in that order. Remember, these are all polishes and not waxes. Meguirs is touted as a wax booster (same, same).

Zaino - Excellant product with plenty of vim and vigor for the price. Application is simple if you know what to do to get started. Multiple products to suit most finish issues. The Z6 speed shine is the best out of all I have tried outside of these mentioned. Rates a 9.99 on the scale from 1-10 as there is always room for improvement. Instructions aren't all that clear, however, once they are known, and the tech support from Sal is exceptional, the process is quick with excellant results. The kits are priced reasonably and last for your money. The result after application is very nice exhibiting good luster and beads well in the rain. No problems result leaving any white residue. BMW CCA discount applies. Nice.

Meguirs NST - Quick. Easiest to apply and remove and in a pinch will get you a nice shine. Very inexpensive IMO and creates good luster but doesn't fill swirls the best out of the three. I found myself going into sections with a soft instrument to get rid of excess polish which added to the detailing time. Beads good in the rain but IMO doesn't last long. Reapplication is required to keep the beading up. Short, but NST was not overly impressive.

Klasse - Most impressive of the three given that it is tailored to the European clear coat (softer than American finishes). The result is more like glass in comparison to the other two. Application is easy, wet the applicator mildly, apply, wipe. No dwell time required. Fills swirls very well, especially on black. Some elbow grease reuired to remove (I did the whole car at once . . . shame, shame), but if you do sections, it comes off much easier and change out your micro fiber often if they are small. I used two 24x40 towels and it came out wonderfully. Excess moisture after the wash does not effect the process and dries up given your towel isn't saturated with polish and water. Klasse says that it will remove old wax, bug grease, etc, but the latter took some work and did eventually come off. I think that would occur with any of them.

Recommendation from Proper Auto Care is to finish with a carnuba wax. I intend on using P21S to finish. I wanted use polish only here to get a feel for what was working and what isn't. Applying the carnuba as the sealant to any of the three will no doubt enhance results. I required no more than an ouce or two to polish (all products) with two apploications and all three do go far for the money. Total time to polish and remove the Klasse was about 30 minutes and a couple Coronas.

Any feedback on similar experiencces would be appreciated or interior detailing products that have been successful (and those that haven't) for you. Thanks for reading.

You forgot about Menzerna too- http://www.properautocare.com/mengerbespol.html

I went with this- http://www.properautocare.com/mecarcakit.html- via John's suggestion at Proper Auto Care and I haven't looked back since. Great product and I swear after I do all three- polish, glaze and wax- the car color takes on a new, more vibrant look. Requires a little elbow work for the polish faze, a little less work on the glaze, and the wax goes on and comes off smooth as silk. Definitely no complaints here on the end result. I'd highly recommend this stuff.

Per John- when you use the polish and glaze, it's best to use the menzerna FMJ as the finish wax.

But one of their packages on their site touts using Final Polish w/ Pinnacle Souveran Wax- http://www.properautocare.com/mensouvkitsi.html. That could be sweet and the good thing about the Pinnacle is that it's made from super-refined Brazilian Ivory Carnauba. That "white" carnauba is the same stuff they use in some of those high-end Zymol waxes.

Or maybe even try the P21S(S100 instead- same stuff except motorcycle version and much cheaper) after the polish. John told me it won't do it after the polish/glaze though.

I'll get around to tryin' those carnauba's one day.

A couple of other good products I use:

Aerospace 303 Protectant http://www.properautocare.com/303-16.html for anything rubber, plastic, vinyl, etc...(interior and exterior) Thanks Orlando Frank for the heads up.

The only place I cheat is my leather- Meguair's Gold Class Leather Wipes. Four wipes do the whole interior- front seats, back seats, doors, etc... Great stuff IMO.

Also, I buy a gallon of this stuff http://www.properautocare.com/hi-c32.html and use a half and half solution for my tires, rims and wheel wells. That gives me a ph of about 10 compared to 9.5 for the super expensive P21S wheel cleaner. Have expensive rims- dilute 3 to 1 for a ph of 8.5. I might try that next and see if I get the same results as the 50/50 mix. I use to use full strength but gave that up after trying the 50/50 mix. Probably do the same after the 3 to 1 mix.

Lastly, this stuff http://www.properautocare.com/mehotshtisha.html is great too. Set it to narrow and spray on to your desired shine. The funk!

Guess I went off on a tangent there- haven't posted for a while I guess. Well, that's it :peace:

Great info. I didn't metion it namely because I've never used it. only the three commented on. However, I have heard nothing but good about Menzerna. maybe that will be next. Thanks.You forgot about Menzerna too- http://www.properautocare.com/mengerbespol.html
