Re: resealing "Old style" Lewmar Portlights
The frames are anodized aluminum but I don't think it would take much to warp them. As far as bedding material is concerned it would be what Beneteau used back in 1998 - can't imagine they would use 5200 (I hope!).
I'll give it a go as soon as we get a dry weekend and report back.
Thanks for all the input!
