Packaging Of The Products

Are you thinking why are we talking about the packaging of these two brands? It’s a necessity, after all.

Both brands have some similar types of packaging. But, marine tex has their products come in a lot of different types of packages. There are products for a variety of things including fixing outboard fuel pump problems.

But, jb weld on the other hand comes in two types of packages. In one type of packaging, jb weld comes in only one container where it’s premixed.

And in the other, there are two containers and you have to mix the two components equally. You’ll be able to apply the epoxy as soon as you mix. But you can’t keep them out for too long.

Marine-Tex Vs. J-B Weld epoxy

But, marine tex works slightly differently here. They don’t have any premixed epoxy. They usually come in 3 different types of packaging and in 2 containers.

In one packaging, you have to mix the resin and the hardener in a 1:1 ratio. And in the other two, you have to mix in a 3:1 or 5:1 ratio. The problem here is knowing which one is right for what.

In that sense, the jb weld is much simpler to use. So, in this section, jb weld is the winner.


Both marine tex and jb weld have a wide range of use. You can use the marine tex on different types of metals. You can even use it on wooden surfaces and fiberglass.

If your keel guard or keelsheild’s sticker starts coming off, use marine tex to fix it. It’ll be a temporary fix though. You should use marine tex because it’s waterproof. You can just change out the sticker later.

We can now say that compared to marine tex, jb weld has a more versatile use. So, in this section jb weld takes the trophy home.


As much as similar types of products these two brands produce, they have different durability.

Marine tex can last for around 10 years. Now, there are few situations here that need to be at play. We aren’t sure if the object went through changes in weather or not.

On the other hand, the jb weld doesn’t have good durability compared to the marine tex. Most known cases of jb weld have lasted for only a year. But, other known cases have lasted up to 3 years.

1-3 years is still good for epoxy. But, compared to marine tex, jb weld doesn’t stand a chance in terms of durability.

So, the winner of this section will be marine tex. If your lever drag reel or star drag reel ever breaks, apply marine tex on it.

The Winner

Now that we’re done comparing the two brands, it’s time to decide on a winner. And the truth is, it’s a tie.

It’s true that jb weld is more used. Not to mention the fact that it can be used on nearly everything. But, in the end, you want something that will last.

If it doesn’t hold for long, there’s no point in using the product.

When it comes to marine tex though, it has hands down the best durability in the market.

But you can’t use it on everything. Its uses are slightly limited and it’s not that convenient to use.

So, durability shouldn’t be the only thing letting marine tex win either.

If you’re looking for versatile use, you should go with jb weld. But, if you’re looking for durability, marine tex is what you’re looking for.
