The Best Rust Converter For a Car That You Should Buy in 2017

Cars are made of metals. Just like in most metals, the cars are likely to develop some rust if not taken care of properly. However, if this is realized early enough, then just a small application of a rust remover will be enough to take care of the problem. At times, it takes too long for one to recognize the presence of rust on the car up to the point that its removal is next to impossible.

The best rust converter for a car is what you need in such a situation. It normally combines with the rust to form a new compound. This compound is always dark in color and very hard. This compound removes the rust, protects the car from rust as well as laying a good foundation for future treatments such as the application of oil-based or water-based paints.

How a Rust Converter Operates

Rust is chemically known as iron oxide. It is a compound that comes about as a result of the reaction between moisture and metals made of iron or its compounds. It becomes so ugly on your car if not removed in time. Balancing and controlling cars with sway control can become difficult if these rusts are allowed to form in large amounts to the extent of increasing the car’s weight.

Rust converters are made from tannic acid that reacts with the rust to chemically convert it to iron tannate. This resulting product is always a stable material that is dark in color. The resulting dark material is a polymeric coating that acts as a primer for both the oil-based and water-based paints. It protects your car from future corrosion and rust.

Types of rust converters

Rust converters are majorly divided into two depending on the form in which they come in. These are the gel and liquid forms. These types of rust converters have their own different features, merits and demerits.

Of the two mentioned types of rust converters, the choice will depend on the nature of the metal surface that is to be worked on. A good example being the time taken to spread the gel types on flat surfaces as compared to the liquid ones.

One advantage that the gel kinds have over their liquid counterparts is that they do not spill so often. The choice between the two is always a matter of preference from the buyer.

Features to Consider Before Buying Rust Converter for Your Car

Rust converters are used specifically on rust and not bare metals. This means that it works best on metals with iron in them. Steel and any other iron alloys are some of the other materials that the rust converter can be applied.

However, there are currently some brands that produce an advanced formula that can be used as primers for the metal surface. The only problem that comes with these formulas is that they will not provide the desired future protection. Medium and heavy rusts are what you should use the converter on, but if the rust is too heavy, then you first need to grind and sand it to become smooth. Here are the key factors to consider.

1. Durability

After the application and curing of rust converter, other activities such as sealing, painting and metal treatment follow. There are currently some rust converters that do not require any form of treatment after they have been applied. They double up as protection from future corrosion. These kinds of rust converters last longer.

The more viscous types of rust converters have been found to be more durable compared to the thinner ones. There is no known standard of measuring the durability of rust converters, but you can gauge this when rust has been converted.

2. Application

Rust converters are thin liquids. They can be applied using a brush or even spray. There are however more advanced brands that come as an aerosol. They are more expensive though. The aerosol types ensure even distribution as well as helping save on the rust converter.

The rust converters have different levels of viscosity since others are thick while others are much thinner. Thinner rust converters are easier to spray compared to their thicker counterparts. The nature of surface you are working on also matters a lot.

It is, for example, easier to spray a long pole than trying to paint it. The thinner rust converters always drip a lot after application and will, therefore, require more coats on the corroded surface before the best result is obtained.

On the other hand, the thicker ones are difficult to apply through spraying, but they stick on the surface without much dripping. This makes them work with just fewer coats. The viscous level of the rust converter and the nature of the surface to be worked on are what will determine the mode of application to use.

3. Ease of cleaning

Cleanup depends on the rust converter’s active agent. Most of them are however made from phosphoric acid-base plus other compounds. These rust converters are the most difficult ones to clean. The surface from which you are cleaning it from also matters a lot.

Based on the surface from which you are cleaning it from, the most difficult to clean rust converters become the easiest if on stone-based driveways. A different scenario is what may occur when the rust converter spills on your clothes or hands.

In this case, the stain will last forever in your cloth and hands until the skin naturally sheds off. There are however some brands that their formulas can be tweaked so that they become easy to clean with just water and soap.

4. Drying time

Generally, rust converters should take between 24 and 48 hours to dry. There are some brands that can just take an hour or two, and you will be able to do some treatment or even painting without any effects on that rust conversion, paint adherence or priming action.

The weather pattern of the area you live in also plays a key role on the drying time of a rust converter to buy. The converters that take less time to dry up are most suitable for areas that are humid or experience rainy conditions. 

5. Side effects

Being that most rust converters are made from phosphoric acid, be assured of some unwanted effects. Direct contact between these rust converters and the skin will in most instances cause inflammation, discomfort and irritation. It is therefore advisable that you use gloves when applying them.

Some rust converters contain some additives that make them non-flammable such as those made from phosphoric acid. However, aerosols are highly flammable due to their compression.
