Car Body Care Tips


So how old, do you think, is this car in the  image? Looks good, doesn’t it? This Mercedes-Benz is 15 years old, with almost 300,000 km (186,000 miles) behind! More than that, it has never been repainted - this is its original paint.

Plus there is no even a tiny spot of corrosion! Now take a look at the next image, it is a three year old car which is already corroded through. Big difference right? So how to keep your car shinny and protect it from corrosion.

Undercoating and rustproofing your vehicle

If you live in an area with high humidity, or where the salt use is common in winter months, undercoating and rustproofing you car can be very helpful. Look at the picture, this is a part of the brake system located underneath the car, it’s completely rusted as you can see.

This is only five years old vehicle from a high humidity, coastal area. Sometimes later one of these brake lines can burst and the car will have no brakes. Properly done undercoating and rustproofing can protect important components of the car from corrosion

How to repair stone Chips

The stone chips if not repaired in time will cause corrosion like in this photo. That’s why it’s good idea to repair stone chips as soon as they appear.

This one is not corroded yet, so we’ll try to repair it. The car is clean and dry and we have all we need - the matching spray paint ordered from a dealer and a toothpick. If you have a touch-up paint with the brush you can use it instead, although I found that with a sharp toothpick you can do more accurate job.

After shaking the spray paint very well (for a few minutes) spray very small amount into the cap Now, slightly deep the end of the toothpick into the paint in the cap. Very carefully, I’m trying to barely fill up the damage with the paint without letting it to come out.

Now it looks much better and it won’t be corroded later.

How to remove deep Scratches

Similarly the deep scratches can be repaired in a similar fashion.

Again, I got the matching paint and using a sharp toothpick I’m trying to barely fill up the scratch.
Now it looks better.

How to remove residue marks

This mark on the bumper was made in the underground parking. If you look very closely it’s actually white paint residue over original clearcoat. The clearcoat itself seems to be damaged only slightly. I’ll try to remove this mark.

All I need for this is ultra-fine 1500-grit or 2000-grit waterproof sandpaper (the higher number stands for the finest abrasive), polishing compound containing mild abrasive (I used the Turtle Wax) and a car wax (I used Turtle Wax liquid car wax with Carnauba).

Very carefully (I don’t want to remove the clearcoat) I sand the marks with wet sandpaper (use only ultra-fine waterproof sandpaper) until all marks are gone. If you have never done it before, try on some small spot to see how it works first.
Now there is no mark, but the clearcoat has lost its shine; I will use polishing compound to restore the shine.

I put small amount of the polishing compound onto the damp sponge and rub well until the clearcoat becomes shiny.

Lastly i buff the area with the car wax.

How to remove minor scratches

Scratches  made by bushes. It’s not a big problem, but… I will remove these scratches in two steps: First, I use polishing compound to polish the scratches. It contains mild abrasive and removes very thin coat of painting. When you will shop for this kind of product, there are few grades available. You need the one that contains the finest abrasive.

Put a little amount of polishing compound onto a damp sponge and buff the scratched area in a circular motion until scratches disappear. But don’t overdo it. I’d suggest trying a small area first, to get used to the process. Then I wash off the area completely.

Squeeze a little amount of wax onto a sponge and spread evenly on the scratched area. Wait a little allowing product to haze, then, using a soft towel, I buff the wax.
