Proper Preparation Techniques: Scuffing the Truck Bed

We’ve seen more bed liners fail because of improper scuffing technique than nearly any other issue. It’s not a guarantee that if you scuff it right there will be absolutely no problems down the line, but not doing it right will definitely cause trouble.

Critical items to note when scuffing a truck bed for a spray on liner:

  1. Apply the wire trim and masking tape first. Since it’s a dusty job, it’s better to have any tape already placed.
  2. Wear a dust mask or respirator. The fine particles will hang in the air and make it difficult to breathe.
  3. Only work in small, easy to finish sections. Don’t try to do a little bit here, a little bit there — you’ll end up forgetting a spot. Working in small sections allows you to see where you’ve done, and where you still need to do.
  4. Pro tip: Do all your truck bed sections in the same order, every time. It’ll become routine, and you’ll gain speed overall that way.
  5. Follow all the contours of the truck bed, leaving no part untouched.
  6. Most importantly — DO NOT scour down to the metal. You’re only scuffing the clear coat, and you want to keep from exposing bare metal. If you do accidentally expose metal, you’ll have to use a primer to cover that part, which is a hassle. 
  7. Remember to blow out all the dust and debris afterward.
