Karen Gross
"Had my brand new 2025 3500 4 door long bed rust proofed and undercoated there recently. Very clean precise work at a very competitive price! Going back in a week to have them install one their tonneau covers with a lifetime warranty. The crew there a very knowledgeable and professional! Well worth going to Pro-Line to protect your new ride!"

"These guys did a fantastic job on my '67 truck. They went over everything I wanted and how I wanted it done. We had a couple speed bumps but they communicated everything and the final result was fantastic! I would certainly go back for anything else in the future."
