I've gone Krown with all my Rams... If you own an Ram (or any new pickup) the tinfoil metal they use to build these new trucks, just to see them rust out in 4-5yrs is insane. The next one (picking up tomorrow) will only be a 36mth lease for 72k (very likely less) and I'll still have it Krowned. I couldn't imagine passing that onto a secondary buyer only to rust away.
I've seen a lot of 09-12 Rams with rockers and boxes completely GONE.. Its unbelievable to me! My 2003 Laramie actually lives 10 mins from me, has almost 300,000 miles on it.. I sold it with around 60k on it .... Literally looks exactly the same as when I sold it. And no I've never spotted it in the local shopping plaza parked, and crept under it.. That'd be weird... but.. maybe I have?! Anyway, creeper or not... for a RAM to last that long without disintegrating in Canada is literally a true estimate to how well KROWN works.
Its a must have. We don't have Ziebart here anymore I don't think, but it sounds like the black tar the dealers also charge $1800 for with lifetime re-touches. While its better to work under a vehicle with because its solid and dries, compared to Krown which is a total mess to work under a vehicle after, i think the dripping effect would allow Krown to be more effective. I used to apply the dealer tar decades ago, and its nicer looking, but doesn't get EVERY little cranny, no matter how good your applicator wand is.
