OK Pal since you are so damn smart tell us why.
And BTW. Stop f*%$ing shouting.
Well, buddy, itís because 5200 and 4200 are prolific and in almost all cases, used for purposes theyíre not designed for. I see countless posts where people are asking which of the two is appropriate for a wide range of uses; the problem is that neither are appropriate. They are truly adhesives. In fact, they are very, very good adhesives. Used in the wrong way, though, they donít do the job right and, once used, often result in damage to the parts the unwitting owner wanted to seal and damage to the boat. For example, ports and hatches - NOT a place where you want adhesive. You want a pliable sealant, such as butyl caulk (if itís a plastic) or 3M 101.
I hope thatís helpful, champ. And I wouldnít shout if I didnít have to, but Iíve made post after docile post on this topic. So, Iíll yell a little. Wait Ďtil I get started on recoring and 2-part polyurethanes. Youíll hear me then, too. Amigo.
did I read 4200 is no good for bedding thru-hulls?
4200 does have uses; though theyíre limited. Certainly thru-hulls are a good use. Iíve used 4200 for a number of things.
Both 4200 and 5200 are great products. They are just massively over-used. Thatís my point.
Thanks MaineSail! I have about six thoughts a day on average. Some are good, some arenít. This afternoon I had (1) 5200 is good for two things on boats and (2) I like bread. I thought the latter wasnít worth posting about. Until now.
You can say that again.
