I have two cans of the same colour, but they are different

Colour variation between cans may be caused by:

• Insufficient stirring of one of the cans.
• Mistint in one of the cans.

If the variance in colour is discovered BEFORE application: 

• Return the can to the store.

If the variance in colour is discovered AFTER application: 

• Remove the stain by sanding or stripping.
