Finishing, refinishing and restoring a finish all take time if you want good results. There is a lot of time spent just getting the surface ready for the new finish.
Restoring a finish takes the longest because not only are you trying to get something to look good again, you're also trying to preserve as much of the original finish as possible.
Glenn is a master at restoration. He has a lot of years of experience in restoring old finishes and it shows in his work.
