Three guides, each covering a decision where the marketing is loudest and the plain answer is hardest to find.
Choosing a polisher
Machine type, throw, and why the wattage figure on the box tells you almost nothing. Includes what else you have to buy before the machine does anything useful.
Pad and compound — a cross reference
The four combinations that cover most correction work, why pad colour coding is not a standard, and how to read a paint before you cut it.
Coating, sealant or wax
What each one physically is, what it honestly lasts on a Canadian daily driver, and the single most expensive mistake in the category.
If you want the vocabulary rather than the decision, the Glossary defines the terms — including the ones that are used loosely on purpose.
