Great Product at a Fair Price
The product is something that I have used for years and like very much. I will comment on something that others have noted in their reviews. The packaging was not up to the job of protecting the cans. Fortunately my order was only slightly damaged. I remember reading the reviews prior to purchasing from this vendor and reading the horror stories about badly damaged shipments. I was on the verge of not buying and moving on but decided to take a chance. I wonder how many sales are lost because of reviews mentioning shipping damage. Also, the poor reviews are consistent and go back a long way. So why does the poor packaging continue?

My 1st epoxy/fiberglass project
This product was easy to use with 1708 Fiberglass rolls. I will reorder in the near future.

Not just for boats - I used it to fix big pond liner
I just repaired a big ornamental pond liner with this resin and fiberglass cloth. I absolutely love the pump feature of the resin and especially the hardener. The pump for the hardener is sized to give you exactly the right amount of hardener for a given amount of resin. Five squirts of resin? Use five squirts of hardener. Easy-Peasy - never too much or too little hardener. It's been two months now, and my pond doesn't leak, and this resin kit made my job easier.

Works perfect.
Awesome product. West systems is always my go to for epoxy pours over my woodwork or into it. When I was a beginner I tried a different brand, a couple actually, but I could never quite get the mixture exact. This system comes with pumps that CAN stay in the cans. Haven’t had a bad mix yet, not saying it can’t happen, but if it does it’ll be on me and not the epoxy. I’m not taking away from the others. They are good products, they just require a couple of separate purchases such as a scale or measurement tools that I personally was hit or miss with. If you’re new to epoxy you really can’t go wrong with these guys.

Works well on my RV floor repair
Okay, this is a very good epoxy. I was working on fixing my floor in my RV with this product. I used the pumps for the first three or four mixes and then just mixed it all. It had about an hour of working time which helped a lot. Sets up really hard and adheres well. Don’t be too rough on the pumps… I broke one being too aggressive with it. Still really happy with this product.

Packaging needs work
The epoxy came in a box, in a bigger box. Not a fan of that to begin with, but the box it comes in has arrows on it to tell which side is up. The outer box does not. The epoxy comes in tin cans sealed with (I believe) cardboard seals. As there is no direction on the outer box my package was delivered arrows pointing NOT up. There was no leakage, but there's a reason arrows are on the box. Had I let it sit in my hot garage for longer it could have swelled up and leaked all over. Not a good way to spend $200, plus my floor would need repair from the epoxy mixing and possibly sticking the box to the concrete. No fault of the delivery driver, at all. As for the product, I've used it in the past and have nothing but good experiences with it.
