Hardener belongs to a two-component reaction
A compatible hardener is used with a designated 2K coating such as a 2K topcoat, primer surfacer or clear coat. It forms part of the coating reaction and should be treated as a specified system component rather than a general-purpose additive.
- Identify the selected 2K coating
- Confirm the designated paired component
- Follow the applicable technical data sheet
Thinner supports application adjustment
An automotive paint thinner is used where the product system calls for application adjustment. The appropriate choice depends on the coating and working conditions described in the relevant product documentation.
- Check coating compatibility
- Consider the intended repair process
- Avoid assuming all thinners are equivalent
Evaluate the complete coating combination
A meaningful coating review records the primer, color, clear coat, hardener and thinner used on the panel. Changing one supporting component can make an otherwise useful comparison difficult to interpret.
- Keep evaluation components consistent
- Record the complete material combination
- Compare application and finished appearance
