Buff and compound type

If there is a light scratch on a company car, it will cost a lot of money to have it repaired. So, it may be worth using an electric polisher to polish the body and make it less noticeable. There are various types of buffing pads and abrasive compounds that can be attached to polishers. Make sure to use them according to the size of the scratches and your purpose.

Types of buffing pads

There are two main types of buffing pads: wool and sponge (urethane). The characteristics differ depending on the material and the roughness of the mesh, so choose the right one for your purpose. Also, since there are differences in diameter and thickness, choose the size that matches your polisher. It depends on your preference, but we recommend a thicker type for beginners. Let's take a look at each type.

Wool buff (hard type, soft type)

Hard type

ハードタイプ

Soft type

ソフトタイプ

This buff is made of wool and is available in two types: hard and soft. It is characterized by its extremely high polishing power and excellent cutting ability. It is used for rough initial polishing, scratches or water stains during car washing and other large damage. Since it has a strong abrasive power, please be careful not to scrape too much and leave scratches (buffing marks) on the paint film. In particular, the hard type has the highest polishing power among buffing pads. It is recommended that it should be used carefully while observing the condition.

Extrafine ~ ultrafine particles

極細目~超微粒子

Sponge buff is a fluffy buff made of urethane material. It is classified into medium, fine, fine (uneven), ultrafine, and ultrafine particles according to the roughness of the mesh. Overall, it has less polishing power than wool buff and is less likely to leave a  scratch. Among the sponge buffing pads, the roughest ‘medium’ type, is used to remove shallow scratches and water stains that do not require the use of a wool buff. The ‘fine’ type has moderate hardness and is recommended for intermediate polishing after initial polishing. The uneven type can reduce the heat of friction when polishing. Extrafine - ultrafine particles buffing pads are fine and very soft, so they are suitable for finishing polishing and application of coatings and waxes. 

A point of note is that excessive polishing may cause the paint to peel off, so it is advisable not to over polish.

Type of compounds

A compound is a liquid or clay abrasive. It is easy to imagine a cleanser used to polish stainless steel. The particles contained in compounds come in various sizes and have different characteristics depending on their roughness. It is important to choose the right compound depending on the condition of the scratches, the purpose, and the combination with a buff. Below is a summary of the characteristics of various compounds and recommended buffing pads.

Medium

This compound is very abrasive and is more similar to paint repair than polishing. Since it tends to leave scratches, it should only be used when there are large scratches. Be careful not to over-polish when using this product. Wool buff with high polishing power is suitable.

Fine

This is used to polish relatively rough scratches such as deep scratches and water stains. Paint stains caused by bird droppings can also be removed. It can be used for skin adjustment as well as rough polishing. It is recommended to use a soft wool buff or a medium / fine sponge buff.

Extrafine ~ ultrafine particles

It is used for polishing relatively shallow scratches and removing water stains. It is recommended to combine with the fine sponge buff.

The ultrafine particles compound can be used for finishing as well as skin adjustment. Check carefully as they are often divided into two types: one for light-colored cars and the other for dark-colored cars. For darker colors, buffing marks will be more noticeable. It is recommended to use a compound with fine particles and polish the surface carefully. Using a sponge buff with ultrafine or ultrafine particles will be suitable.

Polishing

This is a compound with very low abrasive power. It is recommended to use this compound when there are no particular scratches on the body, but you want to add shine to the body. Please use a soft sponge buff with ultrafine and ultrafine particles. 

Summary

There are various types of buffing pads and compounds and suitable combinations for each. There is no right answer, so make sure to make a decision based on the condition of the vehicle, the scratches, and the work to be done.
