Dual-action polisher planner

Reviewed Skip to the planner

Detailers matching a polisher to panel size. The decision this page isolates is narrow on purpose: translate job type into a polisher class. Weight, class, and fitment have to match the vehicle before a feature list matters.

This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank RUPES, Griot's Garage, and Flex. It produces an explainable class so RUPES LHR 15 Mark III, Griot's Garage G9, and Flex PXE 80 can be compared as examples of that class.

The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in CTA. This page does not quote a price or rank a brand.

How to use this calculator

Detailers matching a polisher to panel size. Translate job type into a polisher class. If you can answer full-size panels per job, this page can produce a class you can shop against.

What this page will not do

  1. Enter the planning inputs

    Choose a polisher class by recording full-size panels per job. Use real measurements or counts, not a rounded marketing number.

  2. Keep optional extras off until they are real

    This tool has no optional add-ons. If a number is uncertain, calculate a range and keep the more conservative class.

  3. Read the planning class

    Calculate class and treat the headline as a class, not a product name. Matching examples below follow 15mm, Growth, Home, Starter, Mini, and Advanced.

  4. Compare official pages, then verify

    Open the official page for each example in that class. Confirm current specifications, dimensions, and terms. Decision Lantern does not quote a live price or complete an install review.
