J-B Weld MarineWeld Syringe 2-Pack, White, UV Resistant, High-Strength & Impact Resistant, 25ml 2-Pack, 50172-2

I used it to fill a hair line crack that showed up on one side of trailer door frame. I used tape to keep the material from going where it wasn't needed and removed the tape right after applying the material. The finished result was very satisfactory. I new J-B Weld was a good product because I have used it on my boat in the past. Durability is excellent and color matches the fiberglass of trailer.

Great price, arrived quickly. this is a great product and cures quickly and with applicator tube, it is very easy to use. When dry, epoxy is very durable. Much less expensive than at big box stores.

Needed a filler for a crack in a fiberglass mold. This did the job. It cures quickly.

This product sets up well, but not as hard as other epoxies from this company. The packages do not contain a lot of product, but are suitable for smaller repairs, and the adhesion is good. I would recommend it with the caveats above.

This item is wonderful! Works great underwater. I used it on my plastic pool steps, held Great for two years!

works great

Got a hole in the corner of my fiberglass shower pan. I used an oral syringe to suck up the mixed epoxy and backfill the hole for added sturdiness. Waited an hour, mixed a little more epoxy and used the flat edge of a caulk/grout silicone knife to level the top nicely. The epoxy is easy to spread, but thick enough that it doesn't flow downward or outward from holes your fixing. Great tensile strength is a plus when I might accidentally bump or step in this repaired area or put pressure on it cleaning it. Love that it resists water and chemicals, it being in a shower that is cleaned often. Great product. I can see me using this if I have any future fiberglass scrapes or holes.

MarineWeld is a great product to have around when you need a stronger, more durable adhesive than ordinary household glue. The two-part syringe makes it easy to dispense the epoxy in the right proportions, and the 25 ml size is convenient for keeping in a toolbox without taking up much space. What I like most is the versatility. It works well for repairs involving metal and other rigid materials, making it useful for everything from marine equipment and hardware to general repairs around the garage or home. Once cured properly, the bond feels solid and substantial rather than like a temporary fix. The syringe packaging is also a nice touch. It makes application more controlled and reduces the mess that can come with measuring separate containers of two-part epoxy. As with any epoxy, surface preparation and curing time are important. Cleaning and lightly roughening the surfaces before application can make a big difference. This also isn't an instant-grab adhesive, so you'll need some patience while it sets and cures.

Amazing stuff! Used this to stick on a repair panel in a caravan shower. It was recommended by an ex bathroom fitter. So glad he did. Sets rock solid.

I got two packets for an important project. When we opened one, one of the tubes was completely solid. Not to worry, I had an extra one, right? Wrong! That one was also in the same condition. So now we are delayed by a week at least until we get another suitable product, not to mention the financial losses .

Sehr sehr aber gutes Zeug. Da lohnt sich die Lieferung aus England. Gut ausdrückbar gut verrührbar wird nach 40 Minuten gummiartig so dass ich in mein offenes GFK Loch erst füllen und danach nach 40 Minuten mit einer Schraube versehen konnte es hält alles bombenfest. Auf dem Foto mit der Schraube war ein Versuch der Festigkeit.

Funcionó a la perfección

Works really well, but is finicky to mix...mix too much, and it hardens before you can get it on what you want to glue, mix too little, and it never sets. You will probibly use 1/4 of the tube just getting used to it. After it dries, you can carve it with a sharp knife, or sand it with FINE sandpaper, I used it to fill the chips in a ceramic white cookie jar, feathering the edges with a wet finger just before it hardened, then carefully shaping with an exacto.
