How well do the decals adhere to the helmet?
They stick very well to the helmet’s surface. The adhesive used is pressure sensitive. The harder you rub when applying them the more they stick. The instructions included with each kit advise you to only apply light pressure when first applying the decals to give you the opportunity to reposition a piece if necessary. Once all the decals are applied to the helmet you should apply pressure one or two more times to set them in place permanently.
