Was easier than I thought... Although I had help from a Professional!!
Ok here goes:
Firstly you'll need some water and soap mixture in a spray bottle, a heat gun a bit of benzine to clean the roof... and of course the vinyl:
Some Benzin:
The black vinyl:
Well Firstly you have to kleen the roof of the car... No dust better result!
Then take the vinyl and spray the sticky part with the soap/water mixture, spray the roof with this mixture as well.
Then lay down the vinyl on the roof and move it to the desired angle...
Then with a soft block rub over the vinyl to get all the air bubbles out... Start from the inside(middle) working your way outwards.
Once all the air bubble is out, cut the major excess off.
Then with the heatgun and your soft block rub out the rest of the creases...
So the vinyl takes the curved shape off the roof.
Then with a sharp "blade" cut off the excess on the lines of the roof... sp no extra vinyl is on the edges...
Wipe the vinyl with the benzin cloth to get all the dirt off...
Leave it in the sun for a day or to to dry out completely... In my case it was crappy weather over the weekend so....
The end result should look like this...
