J&F is simply fantastic. After researching how to fix my convertible top and watching a few YouTube videos, I tried to replace all of my leaking actuators. All was going great until the last pin on the last actuator. I reached out to Klaus at Top Hydraulics who sold the actuators, and he patiently helped me with some ideas for getting a stuck pin unstuck. Nothing worked, so he suggested reaching out to Charlie at J&F who he had the highest regard for. Charlie explained that they don't typically work on convertible tops but immediately offered to help on this last pin when he heard the predicament. The mechanic, I believe it was Wayne, troubleshot the issue with expert skill and installed the actuator. Problem solved. I was not even an established customer, so imagine how well they treat established customers. Will be back.
