sounds alot like acrylic floor wax
I used to use acrylic floor wax on my pearson 30. the hull was very dull ,nothing would make it shine.I watched this old timer with the same problem paint this clear liquid on his hull and the boat just glowed.I asked him what he was using and he said "my wifes'kitchen floor wax.So of course I ran to the super market,bought a bottle and tried it.Worked great,did not have any water stains on my bow from that point on & the hull finally had a shine.Just be aware that My cost at Costco was about $6.00 For a full gallon of commercial acrylic floor wax and the same cost for the remover.Big diff compared to $54.00 for a quart of poliglow,next time your at the boat store or at a boat show,open a bottle of that and any similar product and take a whif,it will smell just like your wifes acrylic floor wax,did that a few times and embarresed the guys trying to sell the same stuff for insane mark ups,
