The KS-041 Schutz Gun is for Spray in Truck Bed Liners, Under Coating, or Chip Guard. This Gun fits the 1 Litre cans, 3M Quart / Litre Cans. "WILL NOT" Fit the Raptor Bed Liner Cans.
I received the spray gun in a timely fashion put in my air adapter and sprayed my front bumper, worked as it was described no issues, cleaned it up ready for the next project.
