Using a spray-on bed liner does not necessarily give you negative results. When you are going to use a bed liner spray, follow these instructions to avoid the aforementioned problems-

What to do:

  1. Give the truck bed a thorough clean – the best clean is done by removing all accessories and debris. Clean the back with a grease remover, and you need to do this before you do the masking.
  2. Masking – here you can use the WireTrim Edge Cutting Tape as it requires no knife trimming and for extra protection use masking paper or plastic masking film to cover up windows and holes.
  3. Sanding – you do this to give the truck bed a longer life. With a sander, you carefully hand sand the truck bed ±2-inches inside the masking and finish it off using a 5-inch cup brush attached to the sander. After completion, use an air gun or dry rag to remove the dust from the truck bed. You can give it a final clean with a bonding agent as it is an adhesion promoter.
  4. Prepare the solution and use a low-pressure spray gun – apply a low-pressure coating with multiple passes as it allows the protective layer to create a promising layer.
  5. Remove the trimming – remove the cutting tape and the rest of the masking. Now you can finish the edging and use a black paint market to do touch-ups.

An important thing to remember, always follow the instructions of the spray-on bed liner brands you are using and preferably do it in a closed up area with ventilation for safety. On the other hand, if you do not want to go through the whole process, there are other options available i.e drop-in, bed rug, and bed mat.
