I called around just about every rustproofing place around the coast to ask how they cleaned underneath the car before rustproofing and Colin was by far the most extensive. He took the time out to explain the whole process to me and was happy to share his knowledge and answer all my questions. Colin goes an extra mile to make sure everything is done properly. A great genuine guy with good quality honest work. Very happy with the result. Have already recommended him to my friends and family.
