[skyphix]

I've never tried the wax-based stuff, but know a couple of people up here that have not liked it (the GM Wax stuff) for external application. Thats all second hand knowledge and it seems to work great inside the rockers and cab corners though so take it with a grain of salt.


As I am sure Hatzie can attest to, up here in New England we can normally basically watch the rust eat these trucks up. I plan on getting fluid film done this fall after a trip to the 4x4 section of the Outer Banks. Local places here pressure wash the underside of the truck before applying the FluidFilm - initial coating they do inside the rockers and other vulnerable areas (i.e. rear fender dog leg on Suburbans) and then subsequent yearly treatments they wash and just do the underside and its 1/3 the cost. I've seen how effective FluidFilm is despite the annoyance and cost of having to get it refreshed so to me its worth it.
