This technical guide provides an exhaustive deep-dive into the selection, application, and maintenance of polishing pads specifically for the harsh environmental conditions of the Australian summer.
The Science of Substrates in Extreme Climates
In the Australian context, specifically during the peak of summer, the performance of a polishing pad is dictated by its ability to manage heat and mechanical friction. Our intense UV radiation accelerates the oxidation of clear coats, often resulting in a 'chalky' finish that requires aggressive correction. Furthermore, the presence of abrasive silica in red dust and the corrosive nature of coastal salt spray mean that a pad isn't just a tool for gloss; it is a decontamination and restoration instrument. Using the wrong pad in 35°C+ heat can lead to 'pad failure'—where the adhesive bond between the hook-and-loop backing and the foam softens, causing the pad to fly off the machine or disintegrate. This guide focuses on selecting pads that breathe effectively to prevent heat transfer to the paint, which is crucial when working on dark-coloured vehicles that can reach surface temperatures of 70°C in the sun. Neglecting proper pad selection often results in 'holograms' or 'buffer trails,' which are particularly visible under the harsh midday Australian sun. By mastering pad cell structure and material density, you ensure that you are removing the minimum amount of clear coat necessary to achieve a mirror finish, preserving the vehicle's long-term UV protection.

Equipment Checklist
Pre-Correction Preparation
Decontamination and Strip Wash
Before a pad touches the paint, the surface must be surgically clean. Perform a strip wash using a high-alkaline soap (pH 10+) to remove old waxes. Follow with an iron fallout remover and a clay bar treatment. Any remaining red dust or grit will lodge in your polishing pad and act like sandpaper, scouring the paint rather than polishing it.
Pad Inspection and Priming
Inspect new or used pads for any 'crustiness' or debris. To prime a fresh pad, apply 4-5 pea-sized drops of compound and work it into the surface with your fingers. This ensures every square millimetre of the pad is lubricated, preventing 'dry buffing' which causes micro-marring, especially on heat-sensitive panels.
Environmental Control
In Australia, you must work in a shaded, well-ventilated area. If working in a garage, use industrial fans to circulate air. Ensure the panel temperature is below 30°C before starting. If the metal is hot to the touch, the polish will dry prematurely, clogging the pad and making removal nearly impossible.
Taping Sensitive Trim
Use high-quality automotive masking tape to cover rubber window seals, unpainted plastic trim, and badges. Polishing pads rotating at high speeds will instantly 'burn' or whiten textured plastics upon contact, creating a permanent blemish that is difficult to fix.
The Professional Polishing Sequence
Selecting the Test Spot
Choose a 50cm x 50cm area on the bonnet or boot. Always start with the least aggressive combination (e.g., a polishing pad with a fine polish). This 'conservative' approach preserves the maximum amount of clear coat, which is your primary defence against UV damage.
Applying Product to the Pad
Apply 3-4 pea-sized drops of your chosen compound near the edge of the pad. Do not over-saturate; too much product leads to 'hydroplaning,' where the pad slides over the paint instead of cutting, and it also causes the pad to become heavy and unbalanced.
Spreading the Product
With the machine off, dab the pad across your 50cm x 50cm section. Then, set the machine to its lowest speed (Setting 1) and spread the product evenly. This prevents 'sling,' where polish is thrown onto glass and trim.
The Working Phase
Increase the machine speed (Setting 4-5 for DA polishers). Use slow, overlapping arm movements (roughly 2-3cm per second). Apply moderate downward pressure, ensuring the pad remains spinning. If the pad stops rotating, you are applying too much pressure or the angle is incorrect.
Monitoring Heat Build-up
After 4-6 passes, stop and feel the panel. In Australian summer conditions, the friction can quickly escalate temperatures. Use an IR thermometer; if the panel exceeds 50°C, move to a different section of the car to allow the area to cool naturally.
Cleaning the Pad 'On the Fly'
After every single section, use a pad brush or compressed air to blow out the spent residue. You will see a cloud of white dust; this is a mix of dried polish and removed clear coat. If you don't clean the pad, this 'spent' material will clump and cause 'pigtail' scratches.
Inspecting the Results
Wipe the section with a 50/50 Isopropyl Alcohol (IPA) mix and a clean microfibre. This removes polishing oils that might be 'filling' the scratches. Inspect with a high-intensity LED torch to ensure the defects are actually removed, not just hidden.
Switching Pads Frequently
A single pad cannot do a whole car in heat. The foam 'fatigues' as it gets hot and saturated. Use 4-5 pads per stage (Cutting, Polishing, Finishing) for a standard sedan. Switch to a fresh, cool pad every 2-3 panels to maintain consistent cutting power.
Managing Edge Work
When approaching panel edges or body lines, reduce pressure. The paint is thinnest on the edges, and the increased friction at the perimeter of the pad can 'burn through' to the primer in seconds. Professional tip: Tilt the machine slightly so the pad rotates away from the sharp edge.
The Final Finishing Pass
Once correction is complete, switch to a soft finishing foam pad and a fine jewelers polish. Use very light pressure and slightly faster arm movement. This removes any slight hazing left by the heavy cutting stage and maximizes the gloss/reflectivity.
Pad Removal Protocol
When finished, do not pull the pad off the backing plate by the foam. This will tear the foam. Instead, use your fingernail or a flat tool to get between the hook-and-loop interface and peel it back carefully.
Deep Cleaning Post-Job
Submerge used pads in a bucket of warm water mixed with pad cleaner. Massage the foam to release the polish resins. Rinse thoroughly until the water runs clear. Spin them on your polisher inside a bucket to 'centrifuge' out the excess water before air-drying.
Avoid Direct Sunlight and Hot Panels
Never attempt to polish a vehicle in direct Australian sunlight or when the panels are hot to the touch. The heat causes the lubricants in the polishing compound to flash (evaporate) instantly. This leads to the pad 'grabbing' the surface, which can cause the machine to kick back or, worse, cause the pad to mar the paint surface severely. Always work in the shade or during the cooler early morning hours.
Beware of 'Pad Explosion' from Heat
In high-temperature environments, the adhesive that bonds the Velcro backing to the foam pad can fail. This is known as 'delamination.' If you feel an unusual vibration or see the pad bulging in the centre, stop immediately. Continuing to use a delaminating pad can result in the backing plate making direct contact with your paint, causing catastrophic damage that requires a respray.
Red Dust Contamination Risk
If you live in regional areas or have recently returned from an Outback trip, be aware that red dust (iron oxide) is incredibly abrasive. If even a tiny amount of this dust remains in a door seal or badge and gets sucked into your pad during polishing, you will essentially be sanding your car with grit. Ensure a 100% thorough pressure wash of all crevices before starting.
The 'Two-Pad' Rotation Method
To combat the Australian heat, professionals use a rotation system. Keep a small bucket of cool water nearby. When a pad gets too warm, swap it for a fresh one and place the warm one in the water (after a quick clean). This keeps the foam cells firm. A 'blown out' or soft, hot pad loses about 50% of its corrective ability.
Compressed Air is Your Best Friend
Instead of using a brush, which can sometimes push grit deeper into the foam, use a compressor with a blow gun. Set it to 60-80 PSI and blow from the centre of the pad outwards. This fluffs the foam and removes 90% of the dried residue, significantly extending the time you can use a single pad before it needs a wet wash.
Match Pad Diameter to Backing Plate
Always ensure your pad is slightly larger than your backing plate (e.g., a 130mm pad on a 125mm plate). This 'overhang' provides a safety buffer. If you accidentally bump a mirror or a trim piece, the soft foam hits it rather than the hard plastic edge of the backing plate, preventing gouges.
Long-Term Maintenance of Polished Surfaces
After achieving a high-gloss finish with your pads, the paint is 'naked' and highly vulnerable to the Australian elements. You must immediately apply a ceramic coating or a high-quality synthetic sealant. In our climate, a standard carnauba wax will only last 2-4 weeks before the heat melts it away. A ceramic coating is preferred as it provides a sacrificial layer against bird droppings and UV-induced fading. For maintenance, avoid automatic car washes with abrasive brushes that will instantly undo your hard work. Instead, use a two-bucket wash method with a pH-neutral shampoo every 2 weeks. In coastal areas, rinse the vehicle weekly to prevent salt crusting. If you notice water stops beading or the paint feels 'rough' to the touch (usually every 6-12 months), it is time for a light 'finishing' polish with a soft foam pad to deep-clean the pores of the paint and restore the hydrophobic properties of your protection layer.
