A great pinstriper could do it, but it would be impossible to keep the stripe thickness exactly the same everywhere. It's just too thin of a stripe. There are decals available that you could use. Check in the model train department for thin stripes like that. *LINK*
Microscale #460-1116 is a sheet of 1/16" white stripes. I'm sure they're thin enough to be bent into the fairly gentle curves on this car. #460-1132 is 1/32" white stripes. Maybe even better.
