Everything is great, like all West products.

It mixes well with the resin, resulting in a good viscosity for processing.

Ambulance repair

For a small repair on my RTW camper, I used Harzer hardener from West Epoxy and covered it with a layer of resin to improve the finish on my repair area. I don't have a boat, just a camper. But it doesn't matter, it's still good.

Easy to dose good result

Ideal for thickening epoxy resin (adjusting viscosity), easy to mix and does not clump. A great product that is highly recommended!

very strong

this product 404 is perfect ,realy very strong, I used it to fill a big hole, and after that to cut a smaller hole,don\'t try to sand it it\'s very difficult.
I mixed it with polyester resin because I wanted to put gelcoat paste.
