If you simply start polishing your car without any prior knowledge, you risk damaging the car’s paint. Or a little less bad – a not perfect result.
This step by step guide is suitable for beginners, but also for advanced users. The basic principle remains the same. No matter if you polish by hand or with a polishing machine eccentric polishing machine .
Why should you polish a car?
The main motivation to polish your car is probably a dull, scratched paint job. By polishing it is refreshed, scratches removed and the shine intensified.
be careful when choosing the polish. This should be silicone-free its. otherwise you might have a great result at first sight, but after a few washes at the latest it will be gone. Because silicone polishes only "smear" the scratches – a permanent scratch removal can only be achieved with an abrasive polish.
Step by step instructions for polishing a car
Now that we have clarified the reason and the principle of operation of a car polish, we can start with the instructions.
Part 1: preparations before polishing
1. Wash the car thoroughly
first, of course, your car should be thoroughly cleaned. For this you should wash your car best by hand. If you don’t have the possibility to wash at home, you should go to a wash box – even a washing machine would be okay as an exception, since the wash scratches will eventually be polished away again.
2. Dry the car
so that you can continue immediately you should dry the car with a microfiber dry towel. These cloths, specially made for car washing, can absorb an extremely large amount of water. The big advantage is that there are no scratches – unlike the way it was done in the past.
3. Knead the car paint
the inexperienced reader will now only understand the meaning of the word "playdoh" and think: "do i have to get my kids playdoh out of the cupboard now??". But no. There are special lacquer cleaning kneads with which you can clean the lacquer "pore-deep" together with a lubricant can clean. You can think of it like those patches for the nose, which remove blackheads.
4. Mask off trim and rubber strips
this step is especially important if you are using a polishing machine. Because the fast rotating polishing sponge can damage plastic parts. Also, car polish can bleach plastic and rubber trim. If you have polish splashes on the plastic, you should wipe them off before they dry. To prevent this, it is advisable to tape off the relevant parts. Special adhesive tape is available for this purpose, which can be easily removed. For most parts of the car it has exactly the right width. If you polish your car by hand, masking is less important. Of course you should still remove polish residues.
Part 2: polishing the car
polishing with the polishing machine is of course a little different from the classic hand polish. Nevertheless, the steps are almost the same. The different speeds of a polishing machine will be difficult to achieve by hand.
1. Choosing the right polish and polishing sponges
here it depends on how the condition of your varnish is. For deeper scratches you should use a coarser polish and a hard polishing sponge. Conversely, for light scratches and holograms, a fine polish and a medium or even soft polishing sponge may be sufficient.
2.apply polish
first apply 4-5 pea-sized drops of car polish to the polishing sponge.
3. Spread polish
then you spread the polish with switched off polishing machine on a surface of about 40×40 cm. (dab the polishing sponge with the polish onto the paint at even intervals over the entire surface). You should divide the whole car into these small areas to achieve an even result.
4. Run in the polish
now the polish can be spread on low level. With most polishing machines this corresponds to stage 1-2.
5. Polish out the polish
once the polish is distributed, the polish is run through on high (level 3-6 on most polishers). The polish is completely polished out when only an oily smear film is visible. polishing is done in a so-called "cross-walk" to achieve the most even result possible (see picture). The individual lanes should always overlap by approx. 30-50%.
Part 3: Protect the paint
1. Cleaning the paint
before you can apply a wax or a sealant, you have to remove the residues of the polish. Only when the paint is 100% free of residues and grease can the paint protection adhere. For this purpose, it is best to use a mixture of IPA (isopropanol) and water – z.B. 70/30 (IPA/water).
2. Apply paint protection
now you can apply the paint protection, depending on whether you have chosen a nano sealant or a wax.
3. Remove excess
if you have applied a wax or a sealant, you can remove the excess product from the paint after a while. follow the instructions of the product manufacturer.
