Despite precise dosing, thorough mixing and 17 C in all areas with a layer thickness of less than 0.5 mm, it remained completely soft. Thicker layers and the rest in the mixing pot have hardened. Hard to use for repairs. The lack of styrene smell and the matching color are positive.
I bought the gelcoat to repair small defects. When using only a few grams but a reasonably accurate dosage of the hardener is hardly possible, since only 2-3% of it should be added. That would be at 20 grams of gel coat about 0.4-0.6 gr. Hardener. How does that work?
