The penetrating epoxy is a great product.
The apoxy sealer worked great. I thinned it with denatured alcohol and you could literally see it being absorbed into the 3/4 marine plywood I bought for both sides of the transom on my aluminum boat. I put the initial coat and then went back over it with a more wet coat. With the cold weather we were having in Texas, I did not touch it for four days. I was impressed to say the least. If a person wanted to spend the time you could have a very slick, hard shine on your wood. I did not have the time and used a d/a sander to smooth out the finish and then painted it. I am very sure this transom will out live me for years to come.

No more rotten wood
Used this to repair rotten wood on my boats engine hatch. It is not solid as a rock. It really penetrated the wood. I did thin it for more penetration and it worked great. Very good stuff. Follow directions and you can’t fail.

works well, but cures slowly so plan accordingly.
Works really well- be sure to follow directions exactly. I bought this epoxy to repair the sun deck transom pad on my 2000 bow rider. the wood became dry rotted at the hinges and was dry and crumbly. I bought the cold weather formula as i was using it in 45-60 degree weather. Its critical to follow the directions as if you get the mix wrong it will not cure properly. Keep in mind this will not be a quick cure- it takes about 24-36 hours to have it cure to the point where you can handle it, so you need to plan accordingly. once it cured i then followed up on the repair with PC 11 marine epoxy to fill the rotted out screw holes. The product works as advertised, but you need patience with it.

Great coverage and remains flexible
I used this to seal a plywood surface on a trailer that carries ATVs. It had been treated multiple times with truck bed paint and so on. I scraped and sanded off what I could. This epoxy was easy to use and did penetrate. I had a few places I spilled on plastic that was covering the floor. The cured epoxy is still a little flexible which gives me hope that this will last a few years outside in the harsh Colorado climate

Exceeds expectations, unbelievable performance!
When mixed as directed and lightly thinned with MEK, the resin easily penetrated dry rot within an 8 x 8 beam and also deeply penetrated the adjoining solid wood mass to form a complete and integrated beam again. When fully cured the result was even better than expected. The resin-imbedded wood withstands incredible compression and increases tensile strength. The treated wood has a scratch-resistant surface and is waterproof and insect resistant to stop future degrading. Saved immense time on having to replace wood. I'd even use this product as a preventative measure with wood in vulnerable situations such as sill plates and ground contact areas.

Great stuff
Kind of a gross story, but when I bought my new house and started renovating it, I discovered that the previous owners' dogs had peed all over the floor for years and it had soaked into the subfloor, which was particle board. I replaced the worst spots, but I just didn't have the money to replace everything. The particle board in the pee-spots was unstable and smelled terrible. I tried various things to get rid of the stink, but eventually had the idea of using penetrating epoxy on the spots to encapsulate the stank and re-stabilize the particle board. This epoxy is thicker than penetrating epoxy I've used in the past, so I did end up needing twice what I thought I would, but I'm happy to say that it worked perfectly! The thickness of the epoxy ended up helping, and it didn't have the same awful chemical smell of other penetrating epoxies I've used. Ultimately it saved me from having to replace my entire floor and got rid of the stench exactly as I was hoping!

Good product, bad shipping
Be aware: my order came wet and leaking. Only lost ~1/8 hardener and neither Amazon nor total boat company stand behind the purchase. So, I would suggest use the product but don’t by from Amazon or have shipped. Bummer really. I’ll try a different company if I need more. Just don’t need the mess!
