I prefer not to use One Shot on any of my hand striped jobs, simply because it has a tendency to flake off in time, because of this it is not a good idea to clear over it either... I would recommend House of Kolor pinstripe paints over One Shot... With HoK paints you can leave them on top of the clear or clear over them as long as you do it within a few hours of laying the stripes down... HoK also uses a hardner which helps keep it on your car rather than flaking off like One Shot does... HoK and One Shot are both very fluid and made to use with a striping brush...

I buried the stripes on my roadster, it took about 9 coats of clear then sanding about 5 of them off to bury the hand painted stripes so that it was totally smooth, remember that hand brushed graphics will be much thicker that layers of paint that have been sprayed on!!!

Here is a link to a site where all the pinstriper guys hang out, I have learned a ton from reading and asking questions on their message board... You can also buy all the striping supplies you need from them... Don't forget to check out their FAQ section for a few tips as well...

Hope this gets you started in the right direction...
