Mid October last year I put down a couple of layers of CG's Jet Seal on my 2000 Silver metallic Odyssey and was amazed not only at how it looked but how it lasted thru one rough Ohio winter. After washing the van last week you could tell it needed to be qd'd (and more)but you could also still see the shimmer imparted by the JS. On the down side it is $$$ but a little goes a long way and it's uber easy to work with
