Easy to apply just take your time. First step is to wash the area you are applying the strip to. I used some windex and a microfibre cloth. Next step is to wipe area with alcohol swab that is supplied. Then you wipe over adhesive primer (supplied) and allow to dry 1-2 minutes. Now pull back the plastic strip that covers the adhesive strip approximately 4 cm from either end and allow the plastic strip to protrude over the top of the weathershield. Align weathershield and stick both ends of shield. You then carefully remove the remaining plastic film and apply pressure along the length of the shield to adhere. I then got a hairdryer on the hottest setting and applied heat along the glued area whilst pressing down on the weathershield to ensured it has glued properly. There were no instructions supplied but I got the information from a you tube clip.
The strips are smoked perspex and were not expensive at around $80 the pair off ebay.
