Review on Meguiar's M5016 Marine/RV Cleaner Wax - 16 fl oz: One-Step Versatile Formula for Superior Results by Kevin Mitchell

Works great as a wax for my old fiberglass Polynesian hot tub. Shines like glass and the spa looks brand new. My spa comes with a treatment kit that includes spa wax. Which is no longer available. Newer spas have a matte finish rather than a gloss finish. This wax appears to be VERY similar. both are hard to get off if you let it smoke all day. I've tried various car waxes and polymers, all of which fail to withstand brominated water. Hoping it will. Will update this review if not.
