After the success of our previous newsletter, and due to popular demand, we had to fill you all in with more details on perfecting your technique!
So, without further ado, here are the four more tips to follow when Polishing and Buffing!
1. “Avoid Hotspots, Hotshot!”
Hotspots are generated when rotary polishers are misused. When pressure is applied to a machine from an operator or the tool is tilted in any direction, more friction is built up causing excessive heat. Hotspots can cause temperature damage to clearcoat and lessen the life of pads. To avoid this problem, pay attention to the angle at which you are polishing. Make sure that your polisher is always parallel to the surface you are working on. If there are sharp body lines, don’t overlap the pad as this will also cause a hotspot and damage paintwork around this area. As a general rule of thumb, if the bodywork is warm to the touch but not burning hot, then you have polished correctly!
2. Keep it Low and Slow
When polishing, maintain a low speed to avoid holograms and swirls, especially on darker coloured vehicles which are prone to these defects. With a conventional rotary polisher, this can be time-consuming. A very fine pad, soft compound and much time are needed to achieve a hologram-free finish. While it is possible to attain this finish with a rotary polisher, we recommend you use a dual action polisher, notably the Rupes Bigfoot Series. The Bigfoot series is proven to reduce the time taken to finish a bodywork by up to 40% and with just one step.
3. Sealing the Finish
The final step in polishing is the application of wax. Although, nowadays PTFE based sealants are becoming more popular as they tend to stay on panels longer. Heat from the environment helps these sealants to bond to the body as opposed to waxes, which tend to disperse from the panel when heat is applied. Waxes do give a deeper gloss finish, but this does not tend to last for an extended period. PTFE based sealants provide a great finish that tends to last for more time. PTFE can also be used on plastic trims as it helps to give that wet look appearance, whereas wax will give a cloudy white appearance.
Anyone who has wax on plastic trim can find it very hard to remove the cloudy smut, but one trick is to apply window cleaner. This can also be used to remove compound or polish stains from plastics.
4. Technique is Key
While everyone has their personalised methods of polishing, there are some basics which can be overlooked by even seasoned veterans of detailing. Posture and movement may sound boring, but they are vital to quality. Firstly, posture; relax your shoulders, keep your forearm and back tight, if any vibrations come from the polisher, your shoulders will absorb them, and a stiff forearm and back will maintain complete control over the tool. When moving, make sure to run slowly and smoothly over the surface, overlapping 50/50 with each new strip as you would when mowing a lawn. Doing this will make definite that you do not miss patches, that the polish is well worked into the body, and spread the polish more, cutting both waste and friction.
If you follow all of the tips discussed in both newsletters, you’ll have no problem perfecting even the toughest to detail bodies.
