In long-term pond sealing it seems that the thicker, more elastic coatings sold as pond lining are very similar to higher quality truck bed liners. In researching and trying high and low grades of pond coatings I see similarities. The poor grades are urethane, polyurethane,a liquid rubbery compounds and asphalt. Good grades are always polyurea or polyurea hybrid. I've repaired a pond with cascade that supposedly had spray-lining called Line-X applied (a polyurea). Line-X appears to be in truck bed liner with a few polyurea types, all of which appeared similar. I re-coated over cracks and leaks with a thicker layer of Seal Tite from Spray-Lining & Coatings which also looked the same except is a more flexible polyurea. Seal Tite is aquatic safe, NSF/ANSI 61 Standards [Drinking water safe] aquaticLIFE™ but SL&C also makes truck bed, jeep, trailer, etc linings which look same except it too is more flexible. Does anyone here have experience with similarities or differences in truck bed vs pond lining coatings?
