All my 1:24 slotcar 0.007" thickness lexan racing bodies were laced. These bodies come clear, so they're painted "inside out". The lace is laid inside the body then the primary color is shot, then the lace removed then the next color is the lace. I used fluorescent green w/silver lace. Looks better than it sounds and was easier for me to see with 7 other cars on a Blue King track at the same time doing sub-3 second, 155" laps with 7 turns.
