Ok, thanks for all the help. Heres the plan, i,ve decided to do a double mask as I thought the first mask will be the hardest as the second is just running the tape up to the first paint line.

Prep car in 400 grit....done.

Mask up stripes.....done. (I used the 6mm tape, it was,nt as hard to get the lines straight and even as I thought) Each stripe is 350mm wide and runs over bonett, over the roof and boot and ass end of the beast.

Next weekend provided I get some good weather.

Put down six coats of the first colour (green), sand with 1200 between the 2nd and 4th coat and finish with 1500 or 2000 after the 6th coat.

Second mask leaving 1mm of green showing.

Put down the black again sanding between every 2nd coat and finish with 1500 or 2000.

Pull off masking and sand off the lip to create a smooth finish with 1500 or 2000.

Six coats of clear sanding every 2nd coat 1200 and finish with 2000.

Buff for a super shiney finish.......
