: My shower stall is lost most of the jell coat. It looks like dirt.It is the finish worn of. We are going to redo : the bath in a couple of years. Do you have any way to paint or coat the stall with untill iredo the whol bath? Thank : You Paul hello Paul, I dont know if this will work for you, but I have a small fibreglass boat which had the same problem. I polished the boat with a product called Tcut which is an abrasive polish used to restore the paint finish on cars, it worked relly well and doesnt cost much, perhaps you should give it a go. Good luck, John.
