Look at Ziebart (do they have those in MA?). I got a full-size Dodge p/u undercoated there for about $200, and they would redo the coating every year before the winter for 5 years free of charge. The undercoating they use is wierd...seems almost like tar (I think it's actually similar to a softer truck bed liner material, maybe someone else could clear that up). It's heavy-duty stuff, and definitely keeps the salt off the undercarriage during the winter. Look at auto-detailing shops...ironically they are the places that do that kind of work up where I'm at. It's tough washing that stuff out of there in the summer (if you were so inclined), but worth it. :rolleyes:
