Having a good time
5/5

Observed a hairline crack on a Denso radiator on my Lexus LX470/Land Cruiser that was 14 months old. had first tried the JB plastic product at a local auto parts store, because it seemed to be the best product available there. This product worked well after the first one did not hold well, so I kept looking until I found it In order to obtain this item, I ordered it online due to its unavailability locally. Here's a tip I wanted to ensure that the resin would set as quickly as possible, so I decided to cut out the resin needed before installing it. In order to mix equally, I applied one part onto each piece of cardboard rather than pouring all of them directly into the bag. If ever there is a crack in the surface, open it up first and then sand it slightly before In order to apply the resin, I used a brush and quickly brushed it on top. I then applied a coat over the top. I've held it with no leaks for 2 weeks now and it seems to work very well! I'm absolutely delighted and confident that the integrity of the site will continue for a long time. Best of luck and work as quickly as possible, but be sure to plan ahead and prepare To cut the cloth, fold it in half.

It is NOT advisable to mix all of them at the same time
4/5

My word is your bond. There is an equal share of each product. In order to mix four different batches, I poured out the liquids. Paper plate with 50 cents dropped on it. To mix with the painting sticks I used, but remember that each 90-second moment is precious! Congratulations, you have completed the task. You don't need to purchase it multiple times if you follow the steps above. I installed it on a plastic top Ford radiator and it worked perfectly. It's okay to take your time. Be careful not to use too much before and before applying the glue, as that goes a long way. I'm positive everything will work out for you.

Make sure that you only use small amounts, as the glue sets too quickly for it to be useful all As long as you do it right, it works
5/5

In order to ensure maximum effectiveness, the mix must be used The reviews provided me with valuable information, including how quickly it begins to set and the recommendation to mix only a tiny The amount left over was half of what I mixed for four servings. The thing that I realized when I worked with my first mix, however, was how quickly it sets, and that's a setup for failure to mix the full amount of black and clear fluids as instructed. There's much more adhesive than what can be effectively worked with before it sets. I sliced off a small corner from each sealed package and squeezed a few drops onto each piece of cardboard after cutting off a small corner The coins should be no larger than a dime to keep them apart. During this time, I was able to wipe off the corner of the package and fold it over a couple times before sealing I only started the chemical process after I mixed the two with the popsicle stick after keeping them separate. The two are quite fluid when squeezed and spread and should not make contact, so give them some room to spread. It is easy enough to see when about equal amounts are present, adding more to one or the other to make it look like an equal amount. The advantage of not using too much is that it saves money. I had a piece of cardboard the size of a business card, and it was stiff enough so I could hold it flat, mix, scrape off the stick along the card edge, and work the combination across the whole piece. Seeing and judging the mixing of the two becomes easy due to the fact that one of them is black, the other clear.
After using the brush to brush the paste onto the prepared surface, I then somewhat scrubbed it into the plastic to invite it to mix and then applied the precut piece of fiberglass mesh, then brushed the mix on top of the At this point it was clear the mix was hardening, and it no longer adhered to the bottom as much. Upon knowing I would need to add additional coats, I stopped working on it and waited until it had set for a little while. This misrepresentation was further exacerbated by the fact that the brush fell apart and was no longer usable due to a result of set up. Since it is fluid when mixed, a thick coat applied to a vertical surface will drain down, adding to the challenge of keeping the coating in place, while applying the fiberglass and coating it, and then keeping that covering in place, all before it sets. The fact that I had planned to apply an additional coat allowed me to properly place the paint. The following day, I was able to inspect the first application after it had set and realized I could improve the coverage and mixed up another serving, applying it using my rubber gloved It is so fluid at the beginning that the mixing process kind of self-levels, as long as one does not apply too much and let it

The plastic tank must be properly prepared when it goes in for the first time. In order to promote bonding, I sanded and smoothed the area beyond the crack. In addition to the crack I had to fill two other cracks. One was about 3/4" long and was located on the flat surface immediately below the upper hose connection tube, the other about an inch long, located above the opening. I sanded, I used a wood burning tool in order to create a more uniform appearance. I used the V-tip to melt about 1/16th of an inch deep into the crack line, then melted the plastic over the crack line. I sanded that surface after it had hardened in order to hide imperfections. It was just a matter of cleaning off the sanding dust with a lint-free rag moistened with alcohol since I didn't have any engine oil to remove. As I applied fiberglass to the round upper radiator tube, I created a ridge when the fabric had been applied at the top. My first coat should have been slightly rounded, so I farmed that edge into a round shape to ensure that the hose seals correctly and applied my additional coat with my finger. I've had my patches for a week and they've held up well, with no sign of failure, and they both look so nicely attached This should be especially true for the edges, which should be permanently attached to the.

There might have been a chance here
3/5

The problem is. In full disclosure, if you have a crack in your radiator tank like I did, you should open up the hole to 1/8" so that the resin can fill in the hole, as opposed to filling it in with a chemical filler. It's not effective to place resin on top of the crack only as it will cause the crack to spread over time. Since there was a crack in the radiator, I could not replace it without removing my $60 radiator, thus making a $15 "band-aid" take the same amount of time Is there anybody out there who wouldn't just replace the thing altogether for $30 more? It will cost you more to fix your crack unless you can get a drill or some other tool into the crack to open it up. This is my complaint, regardless of whether I could have opened up the crack or not, the resin would have dried too fast for it to make much of a difference. With one exception, I followed the instructions to the letter, except for opening the crack. Using a 1. 25-inch wide brush, I applied the resin directly on my 1 inch patch. After mixing the compound for the recommended period of time, I applied it to it. I applied the mesh fabric to the 25"x4" area and before I was able to get the resin fully covered, the resin had already set and was no longer malleable. After all was said and done, I had about 60-70 You need 90 seconds for the resin to dry. Nowhere on the packaging does it say so. In light of what I knew, I might have chosen a different strategy. My patch needed much more resin than I used, I only got to use half of it. So, after all was said and done, the hose patch did not stop the leaking. I revved up the engine and went for a quick drive with it still leaking somewhat. Learn from my mistake, plan ahead and think through your steps, as soon as you squeeze out the resin mix, start applying as soon as you can, maybe even straight from the bag to the affected area, as the resin will begin to set within seconds.

A liquid that never hardens This is junk
3/5

It is a complete waste of time and money to buy this product. The products in the market). A product has been mixed, and I have applied it. The epoxy package got warm as it worked, indicating it was performing its job. After waiting for one minute, I waited for another. The cure time was increased by 5 hours (beyond the recommended cure time). tacky then as well as it was 3 days later (the crack had been dry for 3 days). There seems to have been a mix error. To remove the fiberglass and sticky mess, I had to use a razor blade. Now I'm hopeful that it will at least dry/bond enough to use some other product. The radiator was ruined forever as a result of a simple repair, which resulted in a major repair job. The product is never going to appear on my shopping list.
