Make sure the helmet is clean and free of any grease, oil or dust.
You’d be surprised how oily the surface of a helmet can get when it is handled.
Wipe it with a microfiber cloth to pick up any oil or lint. If needed, use a little soapy water and wipe dry.
Make sure the soap residue is wiped off, too.
Now you are ready to apply the helmet decal.
Remove the backing paper and hold the decal by its edges to avoid touching the adhesive.
Hold the decal flat or flex it slightly opposite the curve of the helmet and gently touch the center of the decal to the helmet surface.
Double-check your alignment and then carefully lay the decal down onto the helmet surface from the center to the edges.
Then use your thumbs to gently slide and press the decal down, always working from the center to the edge.
The best decals will conform to the curved shape the helmet. If you’ve created some air bubbles, don’t panic!
Simply press them away using your thumbs to draw the bubble toward the outer edge until it disappears.
