Good quality clear vinyl protector for roof, or stone chip protection - approx 30 x 100cm, or 12" x 39". First ensure area is clean & free from dust & dirt. Wet the area with warm, slightly soapy water, peel backing from 1/2 of the area you want to cover & start to apply the film from the centre outwards, squeezing out any water/air bubbles as you go (a credit card is ideal for this).
