In an ideal world I'd strip my van to bare metal and apply POR15 on
every single surface. However, this is not an ideal world.
POR 15 is great, and durable, but REALLY particular as to how it likes
to be applied. I really doubt anyone could get the underside of a van
clean enough to do a POR15 application... it really only works on bare
metal.
Ad to this the various overhangs, hidden spots etc, even if you were
to sandblast the whole underside of the van you'd never get into every
crevice,
Chris
