3m 5200

[Mark Major]

As anyone with experience using this product knows it is best for something you never expect to remove. It has its uses, though, but often times an entire tube isn't necessary, and surplus is often is wasted. I did a job today with a tube I opened in March 2010. I seal the ends with aluminum adhesive tape and refrigerate it between uses, and the nozzle can be cleaned out with acetone while the adhesive is still wet.

Mark Major;

You can also purchase the #M 5200 in a small squeez tube for smaller jobs.

I used it alot. One thing I did do was to put a screw or big nail in the end of the tube and wipe off till next usage. It all depends if air can get to it which is why I made sure the material came out of the end of the tube and then inserted my bolt/nail.

If your way is working keeping the 5200 usable, then stick with it as you are fortunate to keep it that long.

Where would anyone use this stuff except for a hull to deck joint? As MS says: it's SATAN'S GLUE!

5200 is not a bedding compound, but a glue. 3m makes a bedding compoun d --is 4200... works well at bedding items needing bedded.

 

[Bill Roosa]

I agree with MS and the others, satian's glue, not to be used as a bedding compound ---unless you like being cussed at by the next owner or cussing at yourself when you have to replace the part.

OK, not as a bedding compound or anything you want to remove, but does it make a good permanent sealant...?

Like on a removed rub rail, to seal the old screw holes prior to installing new rail..?

Or other small exterior holes I want permanently plugged... as opposed to say mixing epoxy and injecting with syringe...?

4200 is not a permanent marine sealant and below the water line, 5200 is permantent. Never had a complaint over the years as I tended to over caulk and then clean up the excess as I did not want anything to move if hit.

I guess we can agree to disagree

I like thickened epoxy for those jobs. Sets up hard and can be faired and painted. POs (probably many) of my boat had filled a bunch of old srew holes in the cockpit with all manner of puttys and caulk. Every one was very visible and it looked like crap.
I drilled out each, cleaned with acetone and filled with thickened epoxy (putty knife, not injected) followed by priming and painting. No sign of the old holes.
I'll bet that once you try using epoxy you'll like it.

It seems to me people fault 5200 for the wrong reason. It does it's job very well. Why fault it for that? I'm going to use it (again) to seal my prop shaft strut when I bolt it back on because I want to be sure it doesn't leak. I used it the last time for the same job because I didn't want it to leak. It didn't leak. The 5200 adhering to the hull when I took the strut off recently (which came right off), was easily removed in under 10 minutes with a dremel tool with wire brush attachment.

Of course it's harder to get off because it stays on better! If you have the right tools to get it off, yeah, it's going to take a LITTLE longer to get off, but you'll never have to worry about it until then. If you have the wrong tools you'll be swearing up a storm, but then what job isn't like that?? I'd use it for every thru hull and any other place in the hull where a leak needs to be prevented. Call me crazy.
