Re: Stus-List Salon Portlight Window Replacement

[Bill Bina]

Adhesives are science, not speculation. 3m specifically says 5200 is not suitable for this application. Limitations: (continued) - 3M™ Marine Adhesive/Sealant 5200 is not recommended for the installation of glass, polycarbonate or acrylic windows that are not also mechanically fastened with a system designed by the manufacturer. Inconsistent adhesion of these unprimed substrates, specific design of the window, and movement due to thermal expansion and flexing, may cause application failure. It is strongly recommended that the customer contact the window/port light/hatch manufacturer for recommendations on proper sealing procedure Bill Bina On 9/6/2013 5:37 PM, Jerome Tauber wrote: As I remarked - there is much debate on the best adhesives to use.   I would not rule out 5200 as you want a permanent installation.   5200 offers, good adhesion and excellent water seal.  However, there is much advice to use a rigid glue so that the windows become part of the structure of the boat.  In my view either would be good for coastal cruising - though a rigid installation is probably the better but more difficult choice.   Just my opinion.   I used boat life boat seal and never had a problem with it.   Use a gun though and a liberal  application.   Jerry Tauber
