J-B Weld 50172 25 ml. MarineWeld Syringe

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.

This stuff does the job you’ve wished others would, but failed. Easy to mix, and easy to apply. Plus once it hardens, it remains bright white, perfect for repairing appliances with minor damage. The cap(s) actually work! That alone is reason to recommend this product. I will definitely buy it again.

So far so good, put a marine board transducer mount on the back of my boat and it is holding so far. Once mixed together is sets up rather quickly and seems to have a good bond between the marine board and my boat.

Works great cured quickly and was easy to apply. They also give you a pretty good amount so having the cap is very nice. It is nice that it can be used on a multitude of materials for future fixes. Haven't water tested it yet, but it seems like it should fix the leak in my son's boat.

Works great - smaller then they used to be- but still good product

Good product

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.

This stuff is great. Sets fast and very strong. Great for gap filling adhesion thats exposed to the weather.

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.
