I can't remember but somewhere I read that that stuff that looks like the stuff we can buy in the tubes is not the same at all.
I have also read things from others whom have a much larger knowledge base (THANK YOU CF!!) than I and I stay away from silicone for the most part.
West Marine (I know but I drove all over the place and could not find anything) had a chart from 3M and on that chart there was a line that said Lexan
, Plastic and in the column it said "NG" for Not Good. This was, I think, geared toward adhesion mostly...........I think.
Note that Lexan
and acrylic are not the same thing except that they are both PLASTIC!!! So is the base of the Nicro vent!!!!! What kind is that???? They say use polyurethane. SHEESH!!!
On the same chart was a listing for 3M Fast Cure 4000 UV and it said "Good" or "Very Good" for the Lexan, Plastic line. The tube itself says " on plastics or paints, test for suitability."
The tube does not say it is polyurethane like the 5200 tube.
So I guess that is what I am going to be doing. I will be mounting two Nicro Day/Night 4 inchers on two Bomar acrylic (Plastic!!!) hatches as a "test for suitability". So there. I will be able to report back in about a week or a month or a few months or a year or, or, or...............
Since the advent of plastic and the rest of the resultant ROCKET SCIENCE in the world things are just not that simple any more.
I will be leaving early tomorrow to do the job. If anyone KNOWS (read that again please) the 4000 is not good please let me know ASAP.
Thanks again all.
