The other one I discovered is TR industries Seapower. I have used Seapower since the early 80's. it's great stuff. TR also has a product called Gel Gloss, found in Home Depot in the tub/shower area. They have RV gel gloss too. All three are the indentical product, simply packaged and marketed differently. Gel Gloss is about $7 for 16oz. Gel Gloss RV is $16/16oz and Seapower is $18-22/16oz depending on where you look.
I use Gel Gloss now
