yes, the blue masking tape works great, what I used first time out was purple duct tape. If you use duct, or vinyl numbers you've got to put a little fresh wax on the paint so they're easy to get back off. My daughter thinks the numbers and stickers are so cool, I've left them on. Kinda sick of 'em but I still have a couple more track days this year. I like the drawn maps so I can print them out (without killing to much ink) keep in the car, or start sketching out a line through the turns. Good luck this weekend !!
