I would not recommend A-1. They did not deliver and after 30 days the tub peeled and bubbled. After sharing my experience, A-1 quoted $700 to refinish work that should of been done right the first time. Poor service, cheap, and poor quality.
Comments were made in the heat of anger. Was unable to modify or delete them. After thinking more on it, kitchen and bath tub were probably not good candidates for refinishing due to age/rust visible. In addition care instructions were probably not followed by tenant. So not sure if A1 Refinishers applications deserve all of the blame.
