Car Polishing Compound Calculator. Polishing compound is easy to waste — too little leaves defects, too much is messy and expensive. Select your vehicle type, polisher type (Dual Action, Rotary, or Hand), paint condition, paint hardness, and skill level in the Car Polishing Compound Calculator to get the exact compound amount needed (ml), plus estimated buffing time, recommended pad type, and total surface area. Also try the Collision Repair Cost Calculator.
Paint hardness determines how much effort and time is needed for correction. Hard paints (German cars) require more aggressive compounds and longer working time, while soft paints (Japanese cars) correct quickly but need careful finishing to avoid micro-marring.

Beginners typically need more compound and time due to learning curve and technique development. Professionals work more efficiently with less waste, while enthusiasts fall in between with good technique but moderate speed.
Wool pads are for heavy correction on hard paints with coarse compounds. Foam pads work best for medium to light correction and finishing work. The calculator recommends based on your paint condition and hardness combination.
Yes, select 'Hand Application' as your polisher type. Hand polishing requires more compound and significantly more time, but the calculator adjusts estimates accordingly for manual application.
Select 'Custom Area' and enter your specific surface area in square meters. Measure the panels you plan to polish for the most accurate compound and time calculations.
The estimates are based on professional detailing standards and typical working speeds. Actual time may vary based on specific environmental conditions, exact compound choice, and individual working pace.
Yes, for heavy defects, the calculator includes time and compound for both cutting and finishing steps. It provides a complete estimate for the full paint correction process.
Dual action polishers are safer but work slower, requiring more time but similar compound amounts. Rotary polishers cut faster but need more skill and slightly less compound due to their aggressive action.
