If your actuator is in rough shape but mechanically still intact we may want to sandblast and epoxy coat the cylinder to it stays fresh in whatever environment you're in. This process is very intensive and takes about 3-5 days. Using a special epoxy formulated for bare metal surfaces is the best protection you can get in the industry. This will be an additional $100 if you decide to have this done.
If your cylinder is frozen solid from corrosion or has holes in it from corrosion please do not send it in, we do an amazing job here but we are not magicians and we do not use JB weld or attempt to weld and reshape parts to make them function for a short period of time. Our crew has decades of experience in the marine industry and if we don't feel its going to last long term we will not build it as our reputation is everything.
