the plastic cover is there for a reason. it provides an insulation against thermal / chemical attacks (ie freezing). PM me if you wanna know how exactly - and how easy it is to defeat a serious lock, I'm not gonna post it up here.
Most of the time it takes longer and is more difficult / risky to remove the plastic than it does to break the lock. to remove plastic you need to carry a stanley knife, and a thief is more likely to think twice about that than carrying the right chemicals to break a D lock.
So do NOT remove the plastic cover, especially if you wanna rely on the guarantee from your lock manufacturer.
Ed, this is terrible advice!
