[Closed] Home respray - flash paint job

I've had a basic respray done to get a nice base colour but want to add a bit extra. I'm thinking of doing something similar to a Blizzard with the head tube and start of the top and down tubes in a different colour with some trailing details of some sort further down the tubes.

I was thinking a can of car touch up paint. Having never done this before any advice on prepping the frame, what type of masking/templates to use and how many coats I'll need etc are welcome..

Thanks
