I haven't really seen a PF housing...but just be careful when using butyl to seal it back up that it isn't the only thing holding the lens to the housing. The facelift housing uses clips with a couple of screws as well to secure the lens to the housing. Im saying this because while butyl is great for providing a water-tight seal, it does get quite soft on a hot summer day; when, coupled with a warm engine bay directly behind it...could potentially cause some issues. just a heads up!
