Review: Sehr sehr aber gutes Zeug. Da lohnt sich die Lieferung aus England. Gut ausdrückbar gut verrührbar wird nach 40 Minuten gummiartig so dass ich in mein offenes GFK Loch erst füllen und danach nach 40 Minuten mit einer Schraube versehen konnte es hält alles bombenfest. Auf dem Foto mit der Schraube war ein Versuch der Festigkeit.

### ⭐⭐⭐⭐ Review
*by C***S on 25 November 2025*

This product sets up well, but not as hard as other epoxies from this company. The packages do not contain a lot of product, but are suitable for smaller repairs, and the adhesion is good. I would recommend it with the caveats above.
