Buyer Guide

How to Evaluate Automotive Clear Coat Samples

A clear-coat sample is most useful when the buyer defines the repair process, paired basecoat and evaluation method before spraying the panel.

Start with the intended repair scenario

A small spot repair, a panel repair and a larger refinishing job place different demands on workflow. Describe the repair size, equipment, application environment and customer type before selecting samples.

  • Repair size
  • Spray equipment
  • Application environment

Use the correct surrounding products

The clear coat should be evaluated over a compatible and properly applied basecoat, with the specified hardener and thinner where applicable. Uncontrolled substitutions can make the result difficult to interpret.

  • Paired basecoat
  • Specified hardener
  • Suitable thinner selection

Record more than gloss

Visual gloss is only one observation. A distributor evaluation should also document application behavior, surface appearance, process timing and how consistently technicians can reproduce the result under the agreed method.

  • Application observations
  • Surface appearance
  • Repeatability and workflow fit

Questions buyers ask

Should clear coats be compared on different basecoats?

For a controlled comparison, use a consistent, compatible basecoat and panel-preparation method unless the purpose is specifically to evaluate compatibility.

What information should accompany a sample request?

Include market, repair type, current coating process, application equipment, working conditions and the products you want to evaluate.
