Well.... I applied some polysulphide to a piece of plexiglass that I have in my office a week or so ago.
It has not "eaten" or even discolored the plex. So there you have it....
Wow impressive data? Did you remove the polysulfide to look under it and see that perhaps the plexi is distorted or showing any signs of crazing on the surface. How long was it there? The plasticizers do not leach out overnight..
I know you feel your right on this so I won't belabor the point. But when the manufacturers advise against the use of Polysulfides on certain plastics I think your "data" leaves room for caution.
Please do me a favor and go back and read what I've written on anchors carefully!
P.S. I also own a Super Max "new generation anchor" that you have NEVER heard me praise! I also never praise the aluminum Spade on setting performance and I do own both a steel and an aluminum version of it. I discuss actual events and actual performance compared to other anchors I own over 30+ years of use for some of them.
Just so you have the facts here are the anchors I have owned or still currently own to base my opinions on:
CQR's, Fortress, Delta, Danforth, Spade (aluminum and steel), Super Max, Luke, Rocna, Bruce & Manson Supreme.
My top five "all round" anchors, in no particular order are; Manson Supreme, Rocna, Steel Spade, Delta & Bruce.
Hows that for frothing?
