Based on my experience, I think that it would be a very bad choice. My boat has 3/8 plexiglass screwed and glued on top of the gelcoat with something like plexus, that sticks very well to gelcoat, but who ever did it could have used a bit more as it leaked in a few places. So I used white 3M 4000/UV to calk along the tops of the windows. After a few years there was no adhesion to the plexiglass at all, and it was very slightly separated along the entire length on all of them. The gelcoat adhesion was still very good.

I am looking to replace my window lenses soon too(likely go w/ 1/4” grey Lexan). I like the idea of using 3M’s VHB tape along with an adhesive/sealant. I have read somewhere (I lost the link) of folks using VHB with black 3M 4000/UV with great results. I have used 4000/UV in the past for deck hardware and hatch rebedding, and I like it’s ease of use. Has anyone use 4000/UV on lexan/plexi windows? I found the link below which provides a nice description of various marine sealants . It specifically lists 4000/UV as well suited for use with plastics. http://blog.dankim.com/2009/04/24/marine-sealants/ - Paul E. 1981 C&C Landfall 38 S/V Johanna Rose Carrabelle, FL On Feb 16, 2015, at 9:20 AM, cnc-list-requ...@cnc-list.com wrote: Date: Sun, 15 Feb 2015 15:59:28 -0600 From: Brent Driedger <bren...@highspeedcrow.ca> To: Josh Muckley <muckl...@gmail.com>, "cnc-list@cnc-list.com" <cnc-list@cnc-list.com> Subject: Re: Stus-List Window Installation - 1985 41 Message-ID: <5fed87b6-6db3-4aa6-af3e-9d24071d3...@highspeedcrow.ca> Content-Type: text/plain; charset="utf-8" Try this link to 3M VHB tapes. http://m.3m.com/wps/portal/3M/en_US/mAdhesives/Tapes/Products/?rt=ms&resultsPerPage=10&Ntt=VHB&x=0&y=0 Brent 27-5 Lake Winnipeg ------------------------------------------------------------------------------ _______________________________________________ Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
