Good Evening gents & gals

In this thread I will be sharing maintenance ideas, tips and info on basic car care - Naturally all contributions are welcome.

To begin with I want to discuss the difference between polishing your BMW and waxing your BMW.

Polish vs Wax

Polish: This is process whereby you remove contaminants and paint defects. The end goal of polish is to enhance the paintwork of your vehicle. Polishes come in many forms ranging from light, medium and heavy abrasives through to polish and wax combinations.

Wax: Wax or Sealants play a vital role in car care as they not only protect your vehicles paintwork from the elements but often also provide extreme amounts of shine and depth to paint which a polish cannot do.

Why is it important to understand the difference?

Understanding the difference between a polish and wax is important because in order to fully enhance the paintwork of your vehicle you require both. Often people use polishes, get their paintwork looking divine and leave it as is. Usually finishes like this only lasts weeks as the newly polished surface is not protected. Wax provides a barrier between the surface of bodywork and the elements, not only further enhancing your hard work but also meaning that you will get to enjoy your shiney BMW for longer.

In this installment I will be running through the difference between a protected (waxed) surface vs an unprotected surface as well as showing you an easy way to enhance your paintwork and protect your BMW.

MK4 Golf - Todays test mule

This car is very poorly maintained in terms of its paintwork. BP Car Wash is the designated place for a wash and vacuum and the car is rarely ever polished or waxed.

As you can see, the paintwork is dull with very little shine.

As per this image from Detailing World your cars bodywork is made up of a base coat, colour coat and then clearcoat. Some paint colours do not even feature clearcoats.

Over time, the paintwork on your bodywork suffers from the elements, poor wash technique and in some cars poor respray work. This is the reason the Golf looks dull and lifeless.

In cars with Metallic & Flat finishes swirling, holograms and paint imperfections can easily remove the sparkle or shine from the paintwork. The reason for this is because your clearcoat on the car has suffered. Imagine a glass window, clear and you can see perfectly outside. Now take sand paper to the glass - Your view outside is now impaired. The same applies to your BMW.

Lets take a closer look at these imperfections:

Swirling, oxidation and Holograms can all lead to less shine and clarity in your paintwork.

How do I improve my car's paintwork?

Polish is your answer, whether it be by hand or by Orbital or if you wish by paying a detailer to have a go.

There are various polishes on the market today ranging from R30 a bottle to R350 in all shapes, sizes and brands. For this Golf I used Chemical Guys Medium Cut 721 polish using a Rotary Machine Polisher. This polish has very good cut allowing easier repair of heavy contamination and paint defects.

Products over the shelf (Game, Makro & Builders) you can use if a beginner:

- Meguires Swirl X
- Meguires Ultimate Compound

Apply the polish using a clean microfibre, working small areas at a time in circular motion. Allow to haze and remove with a clean microfibre. Polishing by hand usually gives good results, however if you can get your hands on an Orbital Polisher it makes life easier.

My results after two passes with the Rotary Polisher on the derelict Golf:

Lets take a look from afar and smile at the difference:

As explained above, your finish is enhanced but this is not the end, no not at all.

Lets take a look at the difference a wax makes not only to water repulsion, but also to the clarity of the paintwork.

Todays wax is Chemical Guys XXX Hardcore White Wax, applied evenly with a microfibre and removed with a clean microfibre. The right side of the bonnet recieved two coats, the left is still unpolished and unwaxed.

Look at the beading the wax creates. Whereas the unpolished/unwaxed area is unable to repel the water causing the water to remain, causing more damage to the finish of the car.

Easy waxes to use are:

- Meguires NXT 2.0 Wax
- Meguires Gold Class Wax (Also contains fillers so hides swirls)
- Chemical Guys 50/50 Wax
- Checmical Guys Wet Butter Wax (Not very durable though)

Beading up close:

With your paintwork enhanced, efforts protected you can now sit back and grin at your BMW:

In the next installment I will hopefully give you a detailed write up a basic wash process so that your newly enhanced paintwork not only remains protected, but also ways to reduce potential paint damage and even more hours slaving over the bonnet of your favourite BMW.

What do you recommend as a good machine polisher that won't eat the paintwork like a baboon handling an angle-grinder? DA polishers, maybe a few examples...

Up until now I have not been brave enough to try out machine polishers for fear of causing more harm than good due to inexperience and not having the ideal polisher. I am sure in the end it isn't rocket science, but is a carefully attained art gathered from trial and error and experience. Maybe some tips, do's and don'ts...

Thanks for this thread - great idea! :thumbs:

Its a pleasure guys.

Will work on the Basic Wash Guide this Saturday and get that posted, it will also include info on wash techniques and what cloths/products to use.

What do you recommend as a good machine polisher that won't eat the paintwork like a baboon handling an angle-grinder? DA polishers, maybe a few examples...

There are a huge variety of polishers out there you can use of which the safest is your standard Shield Orbital polisher from Game/Makro costing about R200. You can pick them up for cheap, they are easy to use (with the exception of your arms going numb mid polishing) and it is virtually impossible to damage your paint with one.

Places like Crazy Detailer also offer these if you wish to have either better performance or want a machine that is more dedicated:

http://www.crazydetailer.co.za/index.php?main_page=product_info&cPath=23&products_id=473

The G220 is an extremely good machine, paired with the right products and knowledge it is very easy to get full correction from one.

Otherwise just stick with the basic cheapy Shield Orbital as they also give great results with minimal effort.

Also keep in mind, and I dont mean this to make you complacent but it takes a lot to burn through paint. This video here shows how long a rotary machine, with a foam pad take at about 3000RPM to break-through:


Hope that helps.

Great Post Legacy!

I was actually going to make reference to those at a later stage, huge amounts of info on that website.

Ah, thanks Mike, thanks Legacy! Was never really 100% sure of how the dual action worked compared to the normal rotary polishers - I think what confused me was the dual head polishers that (was it amazing glaze) were using which had two counter-rotating heads side-by-side as far as I understood.

Understanding this better now it makes me feel a lot more confident to invest in a good quality DA polisher and try my 'hand' at this.

This is a great thread! I hope it grows with knowledge and experiences! :thumbs:

Yeah that dual head one is called the "Cyclo". I have never used one and I don't think I will like it since there is only one speed setting. That being said I have also read it is a very capaple and awesome machine once you get the hang of it.

Apparently their techniques were derived from aircraft polishing... But from all that I've heard, the glaze treatment eventually starts to look ugly, especially on a lighter colour car. Open to correction, but the process also involved polishing most if not all of the clear coat before applying the glaze product... As said, open to correction, but seem to remember something along those lines. But yes, I gather those dual head polishers by themselves were pretty good!

That is some interesting info, I have actually wondered why they would shape the heads that way so thanks! :)

@Mike: Do you mind posting some of you favourite polishes? I can't seem to get my hands on the Menzerna trio so need some other stuff to try out in the mean time.
