Great original product. Works great on the little aluminum boat to patch holes and strengthen up a few spots

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.

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.

Made my Vampire Crab water filter with this stuff. Joined glass to plexi, ,,,and brass to plexi. Handy to have around and with the neat resealable cap,, longer lasting.

Really tough, somewhat rubbery when cured. I used it to seal thermocouple cables through a pressure bulkhead in a vacuum chamber. Good stuff!
