Care and Cleaning of USDOT Number Stickers and Magnetic Signs
Surface Prep (Vinyl Graphics)
The vehicle must be clean and free of dirt before the stickers are applied. This will ensure proper adhesion of the pressure sensitive vinyl decal. Small bubbles can be removed using needle.
Surface Prep (Magnetic Signs)
Clean the steel (magnets only stick to steel) area that you will be applying the magnetic sign with water and a mild detergent. Dry completely. Repeat this process weekly. Wait 2 weeks for new wax to cure before applying.
Once applied, vinyl is virtually maintenance free. Clean your vehicle as you normally would but avoid direct contact with the high pressure spray. Magnets should be removed and cleaned weekly.
