Variety of orbital sanding machines. Difference not to be ignored.

When we speak about different aspects of the car body repairs, usually we mainly discuss the quality of the materials, especially chemicals. No doubt, the final result of any refinishing job depends on paint, clear or primer used. However, it is of utmost importance not to forget how important is the preparation stage, including such a tedious task as sanding.

Just after the Christmas holidays, during the paint preparation workshop in the company’s training center, I came across an interesting question from our customer. This quite an experienced painter was testing different brands of abrasives together with our technical specialist. While I was discussing something with one of our sales manager, I overheard a heated discussion between the painter and our technician. The argument was about using P400 abrasive disc with 5mm orbit sander. “I only use 5mm orbit, and there is no need for any other model”, the painter said with confidence in his voice. “All these different orbit sizes are just made to make us buying more unnecessary tools”, he added. If you ever had an argument with a painter, you probably know that they are hard to convince about pretty much anything. “Show me the difference “, exclaimed the painter. Therefore, we decided to give it a try.

The rule of thumb

Probably you know the recommendations of tools manufacturers. For the abrasives with grits from P80 to P180 use a sander with larger orbit of 5-6mm, while for the finer sanding jobs with P240-P600 – orbit of 2.5-3mm. Some of the manufacturers also offer machines with rather big orbit of up to 10mm for demanding paint stripping operations; however this kind of sanding tools are not common. What is usually missed in those recommendations, it is the explanations behind this information.

In reality the theory behind is very simple. A large orbit allows the abrasive to cover bigger surface and to remove the “picks” of the uneven surface faster and more effectively. On contrary, smaller orbit covers smaller area, but more densely, leaving smoother surface.

From our internal tests, we found that 5mm orbital sander with the same abrasive and all other conditions the same, removes up to 20% more material than 2,5 mm orbit. This is very important especially in paint stripping or body filler sanding jobs. On the other hand, finer grits load up less when used with smaller orbits, like 2,5-3 mm. This allows achieving better quality surface at less time.

Take away

The choice of tools and materials is a painter’s undisputed prerogative, however we all should not ignore the common sense and facts. Doubt is good only when it pushes one to explore and search for facts. If facts are obvious, ignorance in this case is unacceptable. Using recommended sanders will save you time and money. Proved!

Automechanika 2018. Footnotes.

Yet another Automechanika in Frankfurt closed its doors. I haven’t missed a single event since my very first visit to Frankfurt in 2002, but I still feel a slight adrenaline rush when I enter the hall 11, where the majority of the refinishing stands are located. As a visitor and as an exhibitor, despite the decrease of the exhibitions’ importance in our business (actually in any business), I do enjoy the buzz and the energy of this venue. I guess it is in my blood already.

What I enjoy most is meeting people. Many of them I know, many faces are familiar, but we have never had a chance to be acquainted. Nevertheless, the vast majority of the players in our industry are known. “Oh, I remember this guy, he is Greek with a horse brand (Etalon logo features a horse).” – I overheard a whisper in Spanish while in the queue in cafeteria “Bellavista”. In some ways, all the people you meet in the paths of the fair can be divided in three categories: customers (existing, potential and former), suppliers (current, potential or past) and competitors (competitor is always competitor). Meeting customers is probably the most exciting, but simultaneously the most alarming. Where is he going now? I hope not to meet the other guys?

When you return from the event, like Automechanika, you are asked pretty much the same question: What new have you seen? To be short, apart from the long awaited new spray gun from Devilbiss – DV1 – I haven’t seen anything really new. Of course, I could have easily missed something. Correct me please if I am wrong. As you may have heard any business, industry or organization is going through the life cycle in different ways, like revolution and evolution. This process has been described by Larry Greiner in his paper called “Evolution and Revolution as Organizations Grow.” Sometimes this theory is described as Greiner Curve. Revolution is characterized by fundamental change, which affects the way we do something (repair vehicles in our case). Evolution, on the other hand, is an upgrade, an improvement of the existing products and processes. Our industry is going through evolution phase without any breakthrough in the horizon so far. In no way I mean that the evolution is not good; it just underlines that automotive refinishing business is a mature market.

 

While I didn’t see a particularly groundbreaking product, I must admit one significant shift in our trade – much better marketing. For many years, collision repair materials suppliers hadn’t paid attention to the look and feeling of their products. Probably this year’s presentations in Automechanika marked the shift on this matter. The best example is probably the packaging of the newest Devilbiss flagship spray gun DV1. It reminds me the box from the luxury Swiss watch.

Those of you, who attended the fair last week, would probably agree with me that SATA had the most chic stand from all. SATA for some years now dedicates their impressively big stand to a particular theme – “Sweet Sixties” this year. SATA’s team welcomed their guests in stylish uniform, while presenting a dedicated special addition SATA 5000 model. Great job from the marketing team. They totally dismiss a stereotype that everything German is well-built, but boring…

I left the fair with solid feeling that I really enjoy the industry I am in, and, as always, regrettably, I didn’t have enough time to spend with my colleagues, customers, suppliers and competitors (yes, I have very good friends with whom we compete). Friends from Australia, Argentina, Serbia, UK, Albania, Bulgaria, Czech Republic, France, Russia, Ukraine, Poland, Spain, Hong Kong, China, Kenya, South Africa, Italy, Norway, and, of course, from Germany, I will be looking forward to see you soon!
