Last winter I made some parts that latterly 1mth later still hadn't cured... I found if it didn't cure in the first 4 days it never did.
Basically DONT make parts in temps lower than 15deg c is my experience.
+1 - small parts of a comnposite sumpguard I made last winter didn't cure and remain flexible to this day.
Made an oven with a temp controller and never looked back!
