Good stuff
It arrived well packaged, and I think it was good value. After rain showers spoiled my final resin topcoat on my new fibreglass roof, I had run out of hardener but still had plenty of topcoat resin left. This was labelled as MEKP, the same hardener type, so I bought one bottle instead of going back to the original resin supplier for a tub that was far more than I needed as well as more expensive. I mixed a tiny bit to test it (it hardened very quickly), and then went ahead and used it to put my final topcoat on the roof. Great product.
