Menzerna Diminishing Abrasive Polishes



 [: Polishing is the process of creating a smooth and shiny surface by rubbing it or using a chemical action, leaving a surface with significant specular reflection and minimal diffuse reflection. When the surface is magnified thousands of times, it usually looks like mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills." The process of polishing with abrasives starts with coarse ones and graduates to fine ones.]

[Although there is no such thing as perfection; if we work towards perfection hopefully we can                                                 achieve excellence] Vince Lombardi

Menzerna GMBH
Founded in 1888 in Pforzheim, Germany by Friedrich Menzerna to meet the polishing needs of the region's jewellery industry, Menzerna stands today as the leading producer of high quality polishing materials with worldwide presence Building on over a century of application experience and technological innovation, their dedication to quality manufacturing and customer service has earned us the reputation for world-class polishing solutions.
For three decades, Menzerna GMBH has been the factory source for the full line of Menzerna compounds in addition to providing technical product and application information.

Working with PPG, BASF and Mercedes Benz, Menzerna 2003 developed special polishes for use on PPG CeramiClear™ Clear Coat for removing scratches, swirls and paint defects Beyond superior abrasives, Menzerna has pioneered the development of polishes designed specifically for the hard clear coats, like those used by General Motors on the Corvette and PPG CeramiClear™ Clear Coat being used by Mercedes Benz. Super Intensive and Nanotechnology Polish are currently used by Mercedes - Benz in Germany on their production line to remove swirls and over-spray incurred during the painting process.

 A unique family of abrasives developed by Menzerna allows these polishes to remove defects, even on brand new paint finishes, with no loss of surface gloss and no micro-marring. The abrasives are just one factor in the equation; lubricants, solvents, emulsion and their carrier system will determine the actual functional ability of the polish

Process over Product
A wax or sealant can only reflect what is underneath it, so a clean, level well-prepared surface is the most important consideration (85% of a surfaces reflectivity is its preparation) along with applied product clarity. If you apply a product over a surface that is dirty or one that has surface imperfections a wax or sealant will not disguise it, only highlight them.

Always start with the least aggressive / invasive abrasive - pad combination first

Diminishing abrasives require kinetic friction; not heat (that is just a by-product of kinetic friction) to activate and progressively reduce their size until they become a finite milled dust; they are buffered or cushioned in a lubricating water-based oil film emulsion, usually in a semi-liquid paste.
Wet polishes eliminate the friction induced heat caused by buffing; heat causes gloss loss. Some very abrasive compound polishes don’t feel abrasive to the touch because the particles are formulated in a solvent or polymer oils in a water-based emulsion and are not released without friction.

The abrasive starts off as large particles, which removes the most paint, they are then reduced in size into finer and finer particles (hence ‘diminishing’) removing progressively less of the paint surface, by the friction caused by the foam pads contact with the paint surface. By varying the size of the abrasive a differing cut is obtained, so the more the abrasives are reduced in size the finer the resultant finish until the particles are reduced to a very fine powder, which in turn produces a burnished surface shine.

The amount of size reduction (diminishing) can be adjusted by the type of abrasive material used (silica and /or aluminium oxide) allowing some polishes to use for the removal of surface scratches only, but if required can then followed up with a finishing type polish that contains smaller abrasives. Were as some polishes will remove surface scratches and by changing the abrasive ability of the foam pad will then go on to buff the surface to a shine ready for the application of a last step product (LSP)
Polishes are a very essential product for the overall appearance and condition of the paint finish. There are abrasive polishes formulated to remove paint finish issues such as oxidation or other paint surface imperfections such as surface scratches.

Light polishes contain either mild abrasives and / or a chemical cleaner (solvent) most mild abrasive polishes will remove medium scratches or surface imperfections, whereas a strong abrasive compound polish rely both on a chemical cleaner (solvent) l and mechanical abrasives to rectify more serious paintwork issues.

Menzerna Abrasive Polishes

Super Heavy Cut 300 the heaviest cutting and correction compound from Menzerna, bcause it's packed with even more extremely refined aluminium oxide Menzerna Super Heavy Cut is able to remove scuffs, scratches and swirl marks from even the toughest paints.

As with all Menzerna polish it is manufactured using the most uniform shaped abrasive particles, which not only results in a high level of cut, but also a level of shine that shouldn't be achievable from a product with this level of cut. It is so effective at not inducing hazing that it possible on harder paints to go directly from compounding to a finishing product.

It also produces very little in the way of dust and offers longer working times making this polish pleasant to work with.

Menzerna Heavy Cut Compound 400 contains even more ultra-fine abrasive so can now remove sanding marks up to 1200 grit whilst at the same time producing exceptional levels of gloss. We have found this to be a truly exceptional product when used by either Dual Action or Rotary polisher, quickly removing swirls and scratches even on tough paints leaving a truly exceptional level of gloss for such a correction compound.

Cut: 8/10 Gloss: 8/10

Menzerna Medium Cut & Polish 2200 offers an excellent performance in terms of abrasion, but also the level of gloss produced. This product works faster in the medium polish segment than comparative products due to the increased levels of abrasiveness.

Manufactured from precision milled abrasives, this polish from Menzerna makes it the perfect polish for tackling swirls and scratches on intermediate to harder paints by both Dual Action or Rotary polishing machines. The harder abrasives utilised allow removal of swirls on typical difficult to correct paints, whilst creating unparalled levels of gloss which just shouldn't be achievable with a polish with this level of cut.

Cut: 6/10 Gloss: 7/10

Menzerna Medium Cut Polish PF2500 (PO203) this is a highly effective light/medium cut polish for all paint types. Particularly effective on intermediate to softer paints. It contains diminishing abrasives and is also well lubricated so it can work for longer ensuring the abrasives can fully break down fully to remove paintwork blemishes, sanding marks and micro marring even on delicate paints.

Often used as a one-step correctional polish due to its ability to remove surface imperfections, whilst at the same time leaving industry leading levels of shine and gloss.

Cut: 5/10 Gloss: 7/10

Menzerna Super Finish (PO106FA ) is a high gloss swirl remover brings about a new era in polish perfection.

By using a powder fine abrasive, the polish will see off fine swirls and defects and leave you with the most reflective and glossy surface imaginable. Menzerna claim that the abrasives are the smallest and most uniform in the world, these particles have a sharp edge that can cut ceramic clear coats as well as the more conventional clear coats. This means that you get the most stunning shine and gloss imaginable, whilst still being able to remove light imperfections.

Menzerna Super Finish was developed to tackle fine surface scratches in the Maybach and Rolls Royce Phantom and other CeramiCoat finishes. It is however becoming widely adopted as the new standard in finishing polishes, super finish will leave your paint with a mirror shine!

Cut: 3/10 Gloss:10/10


Personal Protection Equipment (PPE)
1.       Eye Protection: I would strongly advise the wearing of safety glasses or visor (prescription eyeglasses are not a substitute) when operating any machine polisher. OSHA requires employers to ensure the safety of all employees in the work environment. Eye and face protection must be provided whenever necessary to protect against chemical, environmental, radiological or mechanical irritants and hazards.

2.       Hearing Protection; the constant pitch of a polishing machine could affect your hearing so wearing ear plugs would be wise to protect you from hearing loss.


3.       Hand Protection; Gloves- with the verity of chemicals a detailer uses on a daily basis wearing chemical-resistant gloves resist penetration and permeation, and will provide protection against dermatitis and chemical burns. Gloves can provide protection, but they must be chosen with care, the proper selection matched to the hazard is critical as they offer a much needed protective barrier when handling cleaning chemicals such as wheel cleaners and multipurpose cleaners.
Nitrile gloves are made of synthetic latex. They contain no latex proteins and offer excellent resistance to punctures and tears. Nitrile gloves are three times more puncture resistant than rubber and can be used to offer superior resistance to many types of chemicals.
Chemical-resistant gloves resist penetration and permeation, and cam protect against dermatitis, chemical burns and corrosion. Nitrile gloves are three times more puncture resistant than latex rubber and can be used to offer superior resistance to many types of chemicals. Unlike other latex gloves, Nitrile gloves have low resistance to friction and are very easy to slide on –

4.       Respiratory Protection (N95): Materials such as aluminium oxide (Aluminium oxide is on EPA's TRI list if it is a fibrous form) or silicon carbide (Nuisance particulate-Accumulation in lungs) used in polishes and compounds, and powdered fillers
Crystalline silica (polishes and compounds) poses a serious inhalation hazard because it can cause silicosis and Isocyanate clear coat residue represent a hazard to your lungs and may cause respiratory distress. Use a NIOSH-approved half face respirator equipped with a combination filter cartridge should be worn while using them
