How to: Properly Apply and Remove Klasse SG

Make sure you have washed your car prior to SG’ing.

In order to apply SG, you should do the following:

1. Take a terry covered foam applicator and spray it with water. Squeeze it as much as you can so that most of the water gone. All you should have is a damp applicator. This will make the SG more pliable.

2. Apply a couple of drops of SG to your applicator and apply it to a section of your car (1/3 of the hood, half of the roof, etc) in a front to back motion. Once you have covered the whole section with SG, immediately wipe off the residue with a DRY MF towel in a front to back motion.

3. Repeat step 2 for every section until the whole car is done.


- As mentioned before, wipe the SG off immediately, no dry time is necessary.

- The SG should wipe off very easily leaving behind a slick, smooth, and glossy finish.

- You should use no more than 1oz. of SG per coat on a regular size car (BMW 3 Series, Mercedes-Benz C-Class)

- Only perform step 1 one time, before applying SG to the first panel. You do NOT need to spritz your applicator with water before applying SG to each section. Once you apply SG to a couple of sections the applicator will be wet enough with SG, negating the need for more water.

-Do not use any water or QD to aid in removal of SG. This will just make the klasse haze down the road. I've also experienced this.

-Wait AT LEAST 24 hours before applying another coat of SG. SG needs time to cure and bond to your paint surface. I would personally wait a week. If you've driven the car ANYWHERE, then wash it before applying the next layer, or else you will just re-swirl your car.

-Put on three coats of SG, and you will be good to go.

-If you desire more warmth and depth in your paint, then apply a carnuba wax a week after you’ve applied the third layer of SG. Make sure you wash before you wax. You may experience some streaking or ghosting of the wax. I did, but it wasn’t enough to bother me. This is because SG and carnuba (any carnuba) don’t entirely get along. Consider yourself warned.

I'd like to add three more things:

1. You can use any pure carnubax wax after your third coat of SG. Just make sure it is not a 'cleaner' wax, or it will strip your SG. Good waxes to use include blitz, p21s/s100 and pinnacle.

2. You cannot add more SG after you have waxed. SG does not bond to wax. Make sure your SG is perfect before applying your carnuba wax. If you really want to add a 4th layer of sg, go for it, but as stated do it before the wax. IMHO, once you wax, you can't go back without starting over from scratch.

3. I'd like to clearly define the difference between dry time and cure time.

Dry time - The time UNBUFFED product sits on your paint before buffing it off.

Cure time - The time BETWEEN buffed coats of a product. Some products like SG require time to cure and bond to your paint before the next layer is applied.

In my article I suggest that SG requires zero dry time, and at least 24 hour cure time.


How to: Using Zaino instead of Klasse in a full detail

So far we all know the basics (see the FAQ above if you don't).

1. Wash
2. Clay
3. Remove swirls with a medium Polish like Menzerna IP (only if necessary)
4. Mild polish with Zaino ZPC Fusion to clean the paint and bring out the gloss
5. Protect the rejuvenated finish with a quality synthetic sealant and/or natural carnuba wax.

For Zaino, steps 1 to 4 will not change. Step 5 will change, and new steps (6, 7, and 8) will need to be added.

If you did not use Zaino ZPC in step 4 then you will need to perform step 5. If you did use ZPC, then you can skip step 5.

Step 5 - Wash with any quality car wash soap to remove the leftover oil/filler/protection from the mild polish used in step 4. You may be wondering why this is necessary if any polish other ZPC is being used prior to Zaino. The reason for this is that most other polishes leave some oil and filler behind on the paint that will shorten the durability of the Z2 or Z5. One winter I applied Z1 and Z5 directly over top of Klasse AIO. When I finally got around to washing the car in April, my Z5 protection was splotchy. Some areas were repelling water very well, while others were pooling. I attribute this to the AIO. I may have applied it a bit thicker in some areas than others (can never get it perfect). Those thicker areas were likely the pooling areas I witnessed when washing. You may also be wondering why/how Klasse SG can work so well over AIO without a car wash in between. This is because they are both made from the same acrylic and work together. AIO will not inhibit SG’s bonding.

Step 6 – Once the wash and dry is complete, you can proceed to begin the Zaino process. This process should go as follows:

1. Mix 1 ounce of Z2 pro or Z5 pro (your choice) with 4 to 5 drops of ZFX. ZFX will allow you to apply a maximum of 3 coats of Z2 pro or Z5 pro all in the same day. Shake very well for 90 seconds. Let the Z2/Z5 and ZFX mixture sit for 5 minutes. Once the 5 minutes has elapsed, shake the bottle again for another 10 seconds. Now you’re ready to apply Z2/Z5. Side note: Do not use more than two ounces of Z2/Z5 and 10 drops of ZFX. Meaning, 3 ounces of Z2/Z5 and 15 drops of ZFX will not work.

2. Place a dime-sized amount of Z2/Z5 on your applicator (I prefer foam applicators covered with short terry strands). Apply the polish in front to back motions on all horizontal panels and top to bottom motions on all vertical panels. If you have trouble spreading the Z2/Z5 evenly, then give your applicator a shot of Z6 QD. Also use the dime sized drop for as many sections as possible before adding another drop of polish. That one-ounce of Z2/Z5 should be enough to do 3 coats on your car. You will end up applying it so thin that you’ll barely see it. Don’t worry; this is how it is supposed to be. A little goes a long way. Let the polish haze for 20 minutes.

3. Once it has hazed, buff it off with any quality MF or cotton towel.

4. QD the car with Z6. This will help remove any Z2/Z5 residue you may have missed. It will also help the next coat of Z2/Z5 to apply easier as well as increase gloss.

Step 7 – Repeat Step 6 two more times.

Step 8 – Finish off by applying 1 coat of Z8 Grand Finale Spray Seal.

Please see the Zaino website for Z8 application instructions.

That’s it! You’re done. Enjoy the beautiful shine!!

Some questions you may have:

Q: Should I use Z2 Pro or Z5 Pro?
A: For light paint colours use Z2 Pro, for dark, use Z5 Pro.

Q: I have some old Z2/Z5; can I still use that instead?
A: Yes. ZFX and Z8 will work with the old formula of Z2/Z5 equally well.

Q: Do I need to use ZFX? Can I apply Z2/Z5 without it? I don’t want to do multiple coats during my detail.
A: No you don’t have to use ZFX but you must use Z1 instead. Z1 is applied the same way that Z2 Pro and Z5 Pro are applied. Once it hazes, Z2 or Z5 should be applied directly over top (do not buff off the Z1 before applying the Z2/Z5, leave it). Once the Z2/Z5 hazes it can be buffed together with the Z1 underneath. This method will limit you to applying one coat of Z2/Z5 in one 24-hour period.

Q: Do I need to use Z1 every time I want to apply Z2 or Z5?
A: No. Only use Z1 after every ten coats of Z2/Z5 or every 6 months, whichever occurs first. Z1 is meant to facilitate in the bonding of the Z2/Z5 to your bare paint.

Q: If I use ZFX and then want to apply another coat of Z2/Z5, do I need to use ZFX again?
A: If you are only going to apply one coat of Z2/Z5, then you do not need to use ZFX again. Just use Z2/Z5 as-is. However, if you plan on applying multiple coats of Z2/Z5 in one day, then yes, you will need ZFX.

Q: Can I alternate between Z2 and Z5? Are the two products compatible with eachother?
A: Yes you can alternate, and yes they are compatible.

Q: Do I really need to use Z8?
A: No. But it will add to the depth and gloss of your paint.

Q: Do I really need to use Z6 between coats of Z2/Z5?
A: No. Again this is just for the extra touch.

Q: Do I need to use Z7 as my car wash?
A: No. Any quality car wash will do. But you will be hard pressed to find a car wash better than Z7.

Q: If I just want bare bones Zaino, what should I get?
A: ZFX or Z1 and Z2 Pro or Z5. That’s it!

Q: Do I need to add a carnuba wax on top of my Zaino layers?
A: No. Carnuba should only be used if you want to alter the look of your Zaino. I personally would advise against topping your Zaino with carnuba. Doing this will negate three of Zaino's four biggest benefits. Those being the slickness, shine, and layerability, with the fourth being durability. Zaino is a product that looks great on its own. I love the look of Z5 on my car.

I think I got everything. If you have any questions, let me know.
