I did the whole bike, execpt the three tank pieces, in 2-3 hours. But i've applied these kits before. A few tips to make it easier.
1. Clean the bike throughly.
2. Use menthilated spirit and a lint free polishing cloth to remove any wax from the areas that will be covered in film.
3. Use a few drops of Johnsons baby bath in a water spray bottle as the wetting solution. Don't use washing up liquid or other detergent.
4. Start with the easy bits. The two knee sections, the top of the tail, the two pieces near the foot pegs and the top of the front faring are flat and give you some practice before you start the curved sections. Leave the sides of the tail section, the sides of the tank and the front edges of the faring until last.
5. Wet your fingers with the solution before doing anthing or you'll get finger prints in the glue on the back of the film. Keep your fingers wet at all times.
6. Wet the area of the bike where you're going to apply the film. Put plenty on, the film should slide about freely when applied.
7. Wet the sticky side of the film as you peel it off the backing and then put it straight on the area to which its going to be applied, before it attracts any dirt. It won't stick to itself if you wet it as you're peeling it off. Take care not to get the backing wet before you peel the film off though or it won't peel off and you'll have a big mess.
8. Apply the film and get it in exactly the right place.
9. Wet the top suface of the film.
10. Use the small rubber squeegee block (should be included in the kit) to start working the water out from under the film. For flat sections work from the middle of the film section towards the edges. Apply more solution to the top of the film if the squeegee is not sliding freely. If it gets too dry you'll damage the film and it will have an orange peel finish.
11. For tougher shaped sections, you need to get part of the film anchored down by expelling the water with the squeege and then use wet fingers to pull the film into shape before removing more of the water from underneath, working away from the section you anchored.
12. Some bits look like they'll never conform to the curves, but they will if you keep them wet and pull the film into shape before expelling the water. You might need to re-wet the surface and squeegee again if they lift after a few minutes. Lift the film and put some more solution underneath if its not going well.
Hope this helps.
