Discolored Hardener

[Madman1978]

Hey, I do not cast a ton, In fact very little. But, I am not sure if this is right.
This is not Alumilite.

They all discolor over time. Do a small test cast and make sure it is still good. It will not affect the end color.

This is less than a year old

It is also half a bottle, exposure to oxygen and sunlight will cause it to discolor. Most data sheets will tell you to use it with XX time of opening the bottle. Some say 6mo, some say use within 6mo of the mfg date regardless of when you open them.
