Questions & Answers

Do you think it will work to fasten galvanized sheet metal to an aluminum boat?

The load will determine the speed. You should be able to bond the pieces together if you remove all the patina (either with sandpaper or wire brush) from both surfaces and there is sufficient bonding area. Please ensure that the joint is securely fastened so that the adhesive can cure fully.

Is this something that may work on a 2 inch pvc pipe coupling that is underwater?

I know what to do maybe if the coupling is under water and cannot be moved, or the water drained, then this is the best chance for a repair. This is something that I would put on after cleaning and steel wooling. The only thing I know is that I am speculating about the situation and how this might work. I am really impressed by the 3M 05220, though. While on the water, it can be used in order to stick stuff on the fiberglass hull of boats, such as speed sensors.

What if I use this ?

No, once your account has been setup you can't take it away

If the adhesive is sanded, will it be damaged?

After it has cured and been fully sanded, it can be painted. This will fill the sand paper a little With any adhesive, the quality of the surface preparation is important as it determines how well it adheres to the surfaces, and therefore how finely it can be feathered.

There's magic here
5/5

A crack developed in the water basin on the toilet while we were replacing the subfloor in our bathroom. As part of the project, we were trying to stay as under budget as possible, and a new toilet would have broken our budget. The interwebs has many handyman resources and I found a forum that specifically asked for advice from someone If your toilet porcelain is barely cracked, here's what you should do. It wasn't reassuring to hear the responses. In general, most advice-givers said buying a new toilet would be wise. 1) "For boats, use the 3M. ". "Hmm, that's interesting. The boat industry uses 3M. How do you think it would Despite my best efforts, I Before the big (little) delivery, I dried out the back of the toilet with towels, and then blew it dry until it was like paper. Two days ago it was as if we were in the middle of the desert. In the course of repairing the basin, we covered the porcelain crack that was long but did not spread. We covered both inside and outside. After layering it on until the caulk was 1/2 inch thick on both sides of the basin, we let it completely dry. Following that, we waited with bated really going to work, or did we just spend $10 on a toilet that we could not afford to replace? The only way to find out would be to wait. A full 72 hours after applying the magic goop, we checked on the outside. It did not have that putty texture that most caulk has but a solid sheath, like one you would get if you bought one at the dollar store. We were optimistic on the first day since there were no leaks. On the second day, the outside of the toilet was as dry as a bone. We've been away from the basin for two months now since our jimmy fix, and not a drop of errant water has been seen. This would be less favorable for a basin that's broken in half, but I am not certain that it wouldn't be sufficient to hold a deeper, wider, and longer crack together.

i love the adhesive for marine applications
5/5

One of my favorite places to go I love marine adhesive, it's great for so many applications. In my boat, a lot of things are 5200 marine plexi, then a screw goes into that. This way, I don't have to drill holes! Whenever I think I might want to remove it someday I dab it into the corners, so I can slide a razor in when I need to remove it. Otherwise I apply it more heavily and it stays almost forever. This stuff can get super tacky quick, so I always wear Your eye will be in TROUBLE if just a little stream hits it! By the grace of God, I was wearing goggles! Although this is true for any adhesive, this one does become stringy/semi-stretchy after a couple of hours You'll need to store the opened tube in a ziplock bag with the cap on tight, and in a cool place, to keep it fresh. It will last a week or so, but not any longer, so it is wise to have your 5200 projects planned out. Getting them all at once is the best way to deal them a blow. The preparation and putting on of protective equipment is also made easier. Make sure you wear gloves as well! Unless you use rubbing alcohol to remove it, it is impossible to remove. It's a match made in heaven! In the interest of cleanliness You're up of excess, and you're on the move. Make sure you have a bottle and rag at hand. This is a bit too touchy for delicate stuff, but great for stuff like that. To be prepared for emergencies on the water, I keep a caulking tube of it and some plexi and wood.

It is impossible to get important information from the ad
3/5

There is a possibility that this product is good, but I may never find out. Upon receiving the product, I read the package instructions which state that I must use the product within 24 hours of opening it. I will utilize it on a number of projects over the next several months, so this is not acceptable for me. for the product that has not been used, but I was informed that it cannot be returned. I don't like the fact that they don't put that in their advertisement.

Having a hard time using
3/5

Seals but does not have a protective coating. I didn't find those techniques to be effective, but maybe they are for other people. A leaky reservoir was found on an outdoor water fountain. This stuff from 3M was tried not once, but twice because the reviews said they were There is something wrong with the reviews. There is still leakage from the fountain. Additionally, once you open the tube, you must use the whole product within a few hours, before it hardens, or it will harden and harden until it can no longer be used. After trying a few different products I ended up getting a different product that requires you to rip off a piece Place the substance like a substance, then mash it in. I was very pleased with how the putty product worked, it was easy to work with, and I can keep the remainder for future use. Overall, I say that it solved my problem perfectly. My future purchases of this 3M product will be my last.

There is no nozzle present
3/5

Since ordering this product five times, over the last five months, I have complained and returned items, and I have called and chatted with the company. In half of the tubes, the nozzles are missing. My old nozzles can now be cleaned and reused since they no longer arrive. ** br>Holy cow, what the heck is going on? Over there, did you even notice I was awake?.

I have used many sealants in the past, but this one is one of the best
5/5

I have used many sealants in the past, but this one is one of the best. A similar product is offered by Permatex, which is 99 to 100% comparable yet significantly less expensive. For marine projects, RV projects, and other uses, I recommend either. Far from being silicone caulk, this is a completely different material. As well as cutting as small an opening as possible, I recommend using an insulated coffin tip. It's really easy to make a mess by applying too much. A slow cure version of this product is also available from 3M I was told to wait 7 days for the treatment to take effect. This is a fact you can rely on. The service is available 24 hours a day. I have used several hundred dollars worth of 3M and Permatex, and find that the cure time works best.
Some are concerned about using them after they have been opened. Be certain to reseal and cap the tube very Several months have passed and I've been holding on to it for reuse. Though I just had a thought, I wonder if, when covered for future use, the tube opening may become harder over time. As I had to drill through the hardened sealant to remove the part, I had to go through the hardened sealant some more.

The underwater light of my pool has been fixed
5/5

A light in my underwater pool kept leaking at the back of the unit where the cord enters. Despite my best efforts, I was unable to seal it. The cord has to be pulled through the conduit all the way and I'm praying it doesn't jam somewhere in between. It's not only expensive but hassle as well as it has to be pulled through the conduit all the way and I hope it doesn't jam. This really did seem worth a shot after I came across it, and I am glad I tried it!.

I am in love with this stuff! Repairing leaky boots is one of the things I have done with it
5/5

I am in love with this stuff! The stuff has been used successfully to patch boots, waders and decoys. It has also been used to reinforce wader soles. I love this stuff - it's the best I've ever used. Why other reviewers complain about being only able to use it as soon as it is opened is beyond me. In my experience, replacing the caps securely at the end of the job has worked when I have used it several times over months.
