There is nothing on a boat that is a never remove solution.
Someone recently told me it was great for something that would never be removed...
The trouble with 5200 is that it is more adhesive than sealant. Hardware mounting is better with something more flexible like 4200. The hardware is attached mechanically, the sealant prevents water from entering and can accommodate expansion and contraction of the hardware with out breaking the seal.
Prohibiting sale of 5200 is the essence of “taking away” a tool.
I raised the issue because there is too much disinformation, misinformation, and plain old rumor mongering on the internet, we all know this. And yes, removing a useful and safe product might be considered taking away a tool. However, in the context of this discussion the comment did nothing to dismiss the rumor and could be construed as supporting and spreading the unfounded rumor. A couple of minutes spent on an internet search and checking on the retail availability of 5200 in California, pretty clearly showed that 5200 is available in CA and there were no reputable news sources that indicated it would be banned.
I don't think this particular discussion has anything to do with "hate", but more likely understanding the products on the market and their proper use. As I said, in my experience, it has almost exclusively been used incorrectly, whenever it has been used on a boat. From filling voids around portholes and hawseholes on a recent 80' build, to filling in around miscut frames and stringers when they built the Spirit of South Carolina, in Charleston, and numerous other cases.
It's the same story with different players, use the right tool and the right products for the job at hand. On a job that needs a good sealant use a good sealant like 4200. On a job that needs a good adhesive and sealant use 5200. At least this "hater" hates to see 5200 used indiscriminately. I'm not sure what thinking drives this especially when the fitting is going to be mechanically secured with nuts and bolts, 4200 or butyl sealant would be perfectly acceptable and much easier to deal with when it was time to remove or service the fitting.
This is simply not true. If it was then get rid of all your epoxy and polyester resin. I agree that it should have a very limited application but it I’d much rather bond two thin objects together than use fasteners when the expectation is that it is permanent..
@MikeHoncho I tried to think of something that is common on boats where 2 things on a boat that might be joined and never taken apart. I couldn't think of anything. The closest I came was a hull deck joint that was glassed over at the factory, but those are rare boats. Even keels have to be dropped from time to time, although this is one application that 5200 is well suited. There may be one-off repairs to broken parts, even there epoxy or polyester resin may be a better choice.
