Why surface preparation matters
Before installation, the bodywork is cleaned, degreased and inspected for chips and dents. Even a small speck of dust or a drop of silicone trapped under the film will become a visible defect.
The main cleaning stages
A two-stage wash, clay treatment to remove embedded contaminants and final degreasing immediately before installation are standard professional practice.
Common beginner mistakes
Using too little degreaser, working in a dusty space and skipping a body inspection under good lighting are among the most common causes of poor results.
