The use of the SMITH SPS10 with the Flail-it medium set-up is ideal, and should achieve an SP 5 - 7 profile with proper up-cut use, best for hot-tape type application on asphalt or concrete. You indicated that you will be removing the stripe and installing it in the same location. If you require a finer profile, it is recommended to have a second cutter drum outfitted with the Strip-it fine pattern that can be used following the Flail-it application to clean out the initial cut.
If you are removing markings and re-applying in a new location, it is recommended to use the LNX8 rotary eraser to prevent sharp-edge permanent grooving where the prior stripe will re-appear as a false ghost line during wet conditions.
It is a best practice to always purchase a wear parts kit and cutter drum assembly or rebuild kit with your new equipment to reduce downtime, and to qualify for the SMITH lifetime chassis warranty. Your account manager, Lauren, can assist you with best pricing.
