personally i'd go with joey's idea. had a landcruiser that was painted with this stuff underneath. killed the road noise and was a rust proofing. easy to apply and doesn't deteriorate or come off.

Yes.. I'd agree that on road vehicles.. you want either a permanent solution or a quick and easy temporary fix.

The questions I'd be asking.. after I'd paid to have the van fitted out after sale.. is why they didn't ask or offer me such solutions to choose from in the retro-fitting planning stages..
