Hello! First time poster. I bought a house with an installed fiberglass pool but the previous owner didn't know anything about it. I found some numbers on the riser to one of the stairs. I couldn't read it even with a mask and snorkel. I tried the old waterproof paper and pencil routine to make a rubbing. It wasn't as successful as I had hoped. I eventually used silly putty to make the impression and now have the entire number. I assume it is the manufacturer and a serial number. The first 3 letters are VPS which I assume is the manufacturer. Does anyone know who that is or a way to find out from the sting of letters and numbers who makes the shell?
