Sorry for the delay...I have bought the large tube three times from Azon, both times 100% good.
I have ordered the smaller tubes more often...problem there is, using enough to keep the content from curing to the point getting the 'hard tube syndrome'.

As far as the 3m Extreme Sealing Tape goes I buy it all at Azon.
It all has been genuine.
See my review here(GOM)...for an explanation direct from 3m.

Fear of fake products on Amazon!
With so many reports of fake products on Amazon, I like to be sure. Thank you for your response and validation.

A comment about Parbond

The sealants have been holding up well on my 2013 trailer. But the sealant around the main door did seem to be deteriorating in places. So I needed something gray that would lay down in a thin layer. I decided to try Parbond.


One plus for Parbond is, it's available in a small 5 ounce squeeze tube (I hate wasting chemicals, and many times when I buy large tube of sealant I wind up throwing away much of the tube because it has hardened on the shelf after I used it).


The big minus is that it's hard to get a neat line of sealant. It seems you just can't tool the stuff. And I don't have a very steady hand. So my finished job doesn't look good.



I do think it seals well. I hope it lasts long.

Another sealant-on-sealant test

I applied a patch of each to a tile, and let them dry for a month. Then I applied a blob of each to each patch, and waited another month. Then I tried to pull them apart. Some stuck, some did not.

The sealants I used were:

1) Lexel. Clear.
2) Silicone. White GE Silicone II
3) Polyurethane. Black Loctite PL S30

The results:
1) Lexel as base layer: Lexel sticks, the others do not (The Lexel product claims to stick to itself, so consider claim verified)
2) Silicone as base layer: Silicone sticks, the others do not (this surprised me; conventional wisdom says nothing sticks to silicone)
3) Poly as the base layer: silicone and poly stick, Lexel does not.

I suppose results might change if the base layers had been left out in the weather for five or ten years......

An update to post 190. The sealants that stuck to each other back then are still sticking today.


I did an additional test with Parbond, applying it to my three old test patches of other sealants. The Parbond stuck to the Lexel very well. It did not stick to the silicone. It stuck to the polyurethane, but I was able to peal it off without much effort.


And an update on Lexel: I still have some left in the squeeze tube I opened in September 2016. I used some on a household project this week. The product flowed well from the tube, and set up well where I used it.

Trempto-635 and Sikflex-221 Both are Excellent Polyurethane products. They work well, stays fairly flexible and last a long time. I use Trempro for large gaps and to bond aluminum to aluminum in conjunction with rivets or screws. Clean up is easy with mineral spirits.

Please read some of the earlier post in this thread for applications and preferences on usage of each product.

I bought one roll Amazon Canada and the inner cardboard liner is blank, procrastinated and still in my tool box for emergency or ??. Just an alert if you are shopping for this product it maybe w/o 3M label. I believe it is 3m just fragments from End-Of-The-Rule .

K.i.s.s.

Just got done reading this helpful post, a lot of information.. In summation, if I'm trying to avoid buying 10 different products and trying to Keep It Stupidly Simple for my limited budget and bandwidth...



Sikaflex 221 for most everything unless...


-I need to remove it in the future...then use Butyl tape



-Small Seams use Acryl-R


-Rivets Sealer use Captain Tolley's Creeping Crack Cure


Does this sound like a reasonable approach?

Gluing inner trim piece of outside compartments

I'm getting really tired of putting the inner trim piece of the outdoor compartment doors. I don't think it's a gasket. It looks like it's purpose is to hold the inner compartment against the door frame. Do y'all have a recommendation for gluing this piece in place?

Two points....be prepared to get very frustrated with the Acryl-R, especially when using the rather useless pump, (you can have mine, just pay shipping)😂

I've used 3m Marine Sealants. 5200 for permanent. 4000UV for most everything else.
MarineTex for repairs,(PEX leaks etc.)

Do you a note pattern here?
I see "Cloudsplitter" as a leaky boat.

Parbond Alternative

I had a hard time finding Parbond without pay $20/tube for it so I decided to take a chance on SeamerMate since it's also a gray gutter sealant. I've never used Parbond but I was able to get a nice smooth bead with my finger. I used a plastic syringe to lay it along the lower belt line trim. Below is a picture. It didn't seem to shrink any when drying so here's hoping it lasts a long time as I plan to do the rest of the trailer with it.

I was able to find SeamerMate locally for $5 for a 5 oz. tube.

Seamermate lasts longer and is paintable, the only issue is you have to remove the painters tape immediately after applying.
