Great product- packaging not so much.
Love this product. Used it before to repair old furniture . That said, the resin can was leaking when I received it. Sticky mess in box & on can. Luckily the hardener wasn’t in same box. : ) Cleaned with alcohol and all was ok. The top wasn’t loose so it must have leaked on an airplane under pressure. Suggest seller pack it in zip-lock or something. Still a great product.

This is one of the BEST EPOXY SYSTEMS on the market.
Excellent Resin when mixed with West System 205 Hardner. They also make other hardeners with different cure times , for different applications. I have used this for many indoor/outdoor projects, and have seen it used extensively in the Marine Industry. Its pricey stuff, but it works. Can be used also for lamination of wood projects such as building a transom plate for an outboard motor. I would suggest getting the easy/fill spouts that go on different cans of the West System products. Makes mixing. FOOL PROOF and easy.

Great for woodworking
I use this with the 206 slow hardener to fill cracks and imperfections in solid wood. You can either dye it to a color you want or use it clear as is. You’re going to end up with a lot of bubbles as with any epoxy, but I use a small torch with indirect heat to pop those and get a perfect finish every time. It’s difficult to work with so if it’s your first time I would recommend watching some videos on YouTube or something to learn more before you dive in. But the product works exactly as intended. Don’t expect to fill a large crack all in one pour. Work in stages or you’ll end up with voids. Get the pumps that they sell as well in order to get the perfect mix and make it easier on yourself.

West System led the way in creating an epoxy that is usable by the average diy project person.
Many specialized epoxies are now available for specific uses or conditions. Some have developed epoxies similar to West System that are a 1:1 mix of resin to hardener, rather than the West System 5:1, which can make mixing easier, but with some basic knowledge West System 105 resin has the ability to accept various materials to thicken, and various hardeners to match conditions, making this product flexible to meet the needs of varying jobs. The product was exactly what I anticipated, the seller’s packaging left a lot of room for improvement. I expect epoxy resin, which has potential health hazards, to be shipped in a plastic bag, for containment if the container is damaged in shipment. I also expect packing inside the box to protect the container from damage. My shipment had neither. The can was badly dented, but luckily there were no leaks. I would not buy from this vendor again.

Every shop should have this
Epoxy with its companion hardener is a great product. It can be used for many repair or building projects where a strong, permanent, waterproof bond is needed. Can be used with a wide variety of materials. Make sure to get the calibrated pumps for the resin and hardener. Both the resin and hardener store well after opening.
