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.

Note "mixing tray and stir stick" is an indentation on the plastic overwrap and a rounded wood stir stick that won't get into the corners of the "mixing tray". I wouldn't waste your time. I used a silicone glue tray (bought on Amazon). https://www.amazon.com/dp/B089QRP6J6 The glue cleans up readily with acetone. This mixes to a glue that is somewhere in the honey to maple syrup viscosity range, which was great for me, but if you are working on a vertical or overhead surface, the glue will need to be sealed on to the vertical or overhead surface. The color is close to "Polar White". @65F, well within the recommended use temperature, it had not set in 15min. I did get out a heat gun to warm the substrates up to 75F+ to see if it would light off and set. My project did require setting within a few hours. I was disappointed to discover an air bubble about half way into the dispensing. Perhaps 0.3ml? That was annoying, but I was able to press the two sides differently to get the volumes to match up again. As I was mixing a 1/3 of the tube at a time, it wasn't that bad, but a smaller amount might have had an issue. This is a first for me with two part glue syringes. While this has a resealable cap, it is up to the user to ensure that the right plug goes into the right hole, or you risk activating the remaining glue. The twist on portion of the tubes did not match any of the static mixers that I have, which was a disappointment as I had lots of things to patch, and that would have simplified the job greatly.

Fabulous product, lives up to all my expectations - strongest adhesive I've ever used

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.
