You will be able to get it where you get the paint. It is called 3M fine line tape. You can get it anywhere from 1/8" to 1" wide (maybe sizes outside this range but these are the most common. THe most common in my shop is the 1/4", next would be the 1/8" for doing really sharp curves, and intricate masking. Make sure and pick up some good 3M masking tape while you are at it, the cheapo stuff at the hardware store will make a mess of a good paint job. Something else that you might consider is that the PPG paints are rather toxic, an apartment may not be the best place to be painting with them. You might be able to find a local auto body shop and may be able to rent some time after hours in one of their booths. A local shop here got interested in our models and let a couple of the guys bring their planes up there at night at no charge.
