You’re responding to a 2014 post, but you are correct.
Yes, that was mentioned already. That's what "BUMP" refers to in the text above. Because this thread it pops up every single time I hit a search trying to find relevant information.
And if a pilgrim came along and read that thread he would be buying 515 or similar and just might not be happy about it.
Because every single person on this site appears to have his own pet case sealant. But that some that work fine for metal to metal are -not- rated for plastic. And then you have 2000 guys saying "don't use silicone" for gas...
And here comes another silicone that's rated to work. But I don't see where it specifies plastic.
So I bought
Threebond 1184 and will use it and see just exacty how that works. If I had enough scratch to buy one of each, I'd buy another saw.
I've got mine, and I'll use it. I've already wasted way too much time trying to nail one down by the manufacturer or anyone else's opinions. Time to smear and see.
