Is my tube of MX-5 still good to use?

[OverDrive]

I have a tube of the discontinued MX-5, I just spread some on paper and it looks good, no separation of the compound or yellow oil. Am I good to use it? I am hoping mine was not part of a bad batch.

Alternatively, I have a couple of tubes of MX-4, these are even older though, however both still look good and spread smoothly.

Thanks.

Thank you. I’ve slapped a little more on paper to be sure and it looks good, so will proceed to use.
