For anyone who's doing a job involving removing VW underseal, these are a brilliant bit of kit. Combined with a heat gun, they're great for getting the worst of the underseal off - even the springy rubber stuff under the floor and wheel arches. I then go over the area with stripping discs or a wire brush on a grinder. They're 16.99. Be quick, as this is last week's stock. I've bought another one as the one I already have has had a hard life, and it's well worth having another for when it goes pop. From a build thread... this is using a scraper and heat gun, before any sort of stripping disc.
