PC Products PC-7 Epoxy Adhesive Paste, Two-Part Heavy Duty, 1/2lb in Two Cans, Charcoal Gray 87770

Strong Epoxy That Really Gets the Job Done This is one of those products that every DIYer or homeowner should probably keep around. I’ve used a lot of adhesives and repair products over the years, and this epoxy feels genuinely heavy duty. Once mixed, it forms a thick paste that stays where you put it instead of dripping everywhere, which makes it especially useful for vertical surfaces, cracks, chipped areas, masonry, tile, or odd repairs around the house. What I like most is the working time. You’re not rushed like with fast-setting epoxies, so you actually have time to shape it, position things properly, and make adjustments before it hardens. Once cured, it feels extremely solid and durable. I also appreciate that it can be sanded and painted afterward for a cleaner finished look. I found it especially useful as a filler as well as an adhesive. The thick consistency makes it good for rebuilding missing material or filling voids rather than just gluing two surfaces together. A few things to keep in mind: this is definitely not a quick-fix epoxy. Cure time is on the slower side, so patience is required. It’s also thick and a little messy to mix, so gloves and a mixing surface are a good idea. Surface prep matters—a clean, roughened surface gives the best results. Bottom Line: If you want a strong, versatile epoxy for serious repairs and don’t mind waiting for a full cure, this is excellent stuff. Not the fastest product, but very strong and dependable once it sets.

***Updated 12/05/2016***** Looks like the repair on the gas tank didn't last more than a 1-1/2 months. Went out and checked the gas tank on the car yesterday and while the fuel hasn't broken through and started leaking yet. There is an obvious bubble where the gas has escaped the tank and is now sitting between the product patch and the steel. You can push up on it and hear the gas/air going back into the tank. The product isn't wet to the touch yet and there's no gas smell, so it's resisting the gas but in time I imagine it will fail. As noted before, I tried every other product out there for patching gas tanks over the years and had high hopes that this would be my savior. Hopefully the patch will hold till the spring and I will just drop the tank and braze or weld the holes and be done with it. Using the proper safety procedures of course. *** End Update**** I used this product to repair a gas tank that was "weeping" fuel. PC-7 not only fixed that issue but the small 1/8" hole I made with the grinding wheel in the tank knocking down previously applied products. I had previously tried almost all of the products meant to fix leaking gas tanks and they all failed. Either immediately or shortly thereafter. Because it takes 24 hr's to cure @ 73 degrees F and longer when the temperature is below that, I wouldn't recommend this product if your stuck somewhere and need to get the car back on the road in a few hours. But your best chance at a successful and long lasting repair means you'll need to invest some time. The product is easy to mix and has a fudge factor of about 20% so if you add a little too much of one part you should still be alright. As with any repair of this type, the sheet metal has to be dry, free of dirt, oil, grease, and most importantly gasoline. If you use soap or glycerine to stop the leak you'll end up with a poor bond between the metal and the product. Best to drain the fuel from the tank and open the fuel cap to relieve the pressure in the tank Clean, abrade, and clean again. Make sure you see no fuel coming out of the area your trying to repair. I recommend picking up some denatured alcohol from a local big box store. Not only can you use it as the final cleaning step but it helps when applying the product as you can put some on a "gloved" finger and smooth out the product. Or use a acid brush for the same thing. You can also apply heat to the product to make it a little more malleable. Caution use the lowest setting on your heat gun or hair dryer and keep the heat at a minimum. Heat at a temperature of over 100 Degrees F will cause the material to turn into a pile of goop. Also be careful using heat anywhere near a gas tank. Lastly when you've applied the product you'll need to give it time to fully cure before adding gas to the tank. If the product isn't fully cured it will not resist the gasoline and the leak will re-occur. At that point you'll have to start all over again. Being the fall, I waited almost a week which wasn't a problem since the car isn't my daily driver. All in all, the product did what I needed it for albeit it takes longer than similar products on the market. Time will tell if the repair lasts.

Excellent product been using it for years on everything from cast-iron to lead pipes

The Weld product I have used for years suddenly doubled in price so I purchased this. the containers part A & B come in are just fine. No problems there. They have the same consistency as the Weld brand and mix the same. The open time is much longer and the cure time is almost 24 hours but it does indeed dry as hard as a rock. The finish is rough and not glossy like the Weld but I do not see an issue. I can almost shape the with my fingers, so you could say it resembles a mold able putty. Ive only used this one time so I cant completely judge it on a variety of surfaces. But it did work on the first item i used it on so we are 1 for 1.

I love this stuff. Works great to petrify rotting boards on my porch, and then fill the gaps. Instructions provided are good.

Great epoxy paste product. Easy mix. Long working time, even longer than 1-hour. Rock hard next day. Recommended!

Easy to mix. Long working time. I used it to fix sink clips underneath a granite countertop. Was able to apply the epoxy once mixed on the clips and stick them on the countertop. Consistency is like peanut butter. Takes many hours to fully cure but it is holding strong after several months. Perfect for an under sink or ceiling application since it sticks to the surface without having to be held in place. I tightened the clips about 24 hours later once it cured.

This stuff is awesome. I’ve been using it for years. VERY strong. Does not sag. Can use vertically or overhead. You can sand, drip, paint, and more. Just make certain everything is clean and ruffed up a bit. Not a one hour epoxy, but worth the wait. My most recent application was in between skip welds on a irewall recess for HEI distributor

Produit arrivé dans ma boîte aux lettres dans une boîte complètement ouverte. Je ne m'imaginais pas non plus qu'il y ait aussi peu de produit ; les boîtes sont minuscules. Il y en a à peine plus que dans un gros tube de colle. Bien fait pour moi j'aurais du regarder plus attentivement la contenance. Pour du modelisme ça va... pour un bateau c'est autre chose.

لاصق قوي دائم اطلبه

Buen producto cumple con sus especificaciones

Qualität gut, schnelle Lieferung

This is my second purchase. It is absolutely amazing. I have tried too many other products to mention and all a waste of money. I have sealed a cast iron outside pipe, no problem. Moulded plastic to metal. There really is no limit to its ability. Highly, highly recommend. Don't waste your money on products that promise but do not deliver. Setting time is speedy aswell. Thank you one million times.
