I've been told to be VERY careful of the spray cans of
tar/asphalt/bedliner etc.  When sprayed on new-good,
painted service they can be wonderful, but when sprayed
on old,  partly rusted (and perhaps moist) surfaces
(wheelwells of vanagons) they can actually trap moisture
in behind the coating and then you will not see the
rusting out parts till the whole thing falls apart.  If one can
get the area DRY and wire brush off most of the surface
rust, then paint the area with "rust converter", then paint
with rust--inhibiting paint, then top coat, then your
rubberized bed-liner stuff, you might have a chance, but
one can not get up in the seams/joints and that is where
the Krown (oily) rust-inhibitor stuff works very well, it
wicks up into all of the crevices and forms a barrier
against the moisture.  IMHO it is a well spent
CDN$110/year.  For all who live along the CDN border, it
is a worthwhile annual trek.  Malcolm (Halifax)
