Yep.Whether it's base or singlestage it's still good as long as it wasn't mixed with a catalyst.If the lid seeped air it may be a touch thicker needing a little extra reducer but as long as it doesn't have seeds in it it's fine.Seeds meaning it has a seedy texture when it's reduced and it looks like someone dumped a handfull of fine dirt or sand in it.Red tints or tints that are hardly ever used get this way so a slow store can even throw you one of these unknowingly.
