3M 5200 is a permanent marine adhesive sealant. This one is white and comes in a 10 oz cartridge, manufacturer number 051135-06500. It forms a watertight, weather-resistant seal on joints and boat hardware, and it is rated for use both above and below the waterline. The figures that matter when choosing: Shore A hardness is 68, and it is tack-free in 30 hours. Handling strength comes in 48 hours. You get up to four hours after application to work it with a trowel or spatula. Prime metal surfaces before use. It softens with heat and should not go in applications over 190°F. It is not recommended for glass, polycarbonate or acrylic windows unless they are also mechanically fastened.
Our take
This suits joints and hardware you never expect to take apart again, above or below the waterline, where a watertight seal matters. Skip it for anything you may need to remove or re-bed, because the bonds are virtually permanent. Keep it away from hot spots over 190°F, and don't rely on it alone to hold glass or plastic windows.
