yes, this is a single line. I have used the multiple lines before and pulled the lines to be painted but this time I don't have that so will lay down 5 single lines of tape butting against each other and pull the two to be painted off so I get a perfect 1/8 inch width of the line everywhere. Also going to make a "32" in a break of the lines in middle of back of car. Will print out the "32" in the size and font I like on my computer, and use a knife to cut the numbers out of the paper, use tach spray on back of paper to stick it to the car so I have a perfect stencil to spray paint the "32" with.
