Very happy with POR15 so far. Bought my Wrangler in 2014, noticed some rust under the car in a few months since the purchase, and sought after the answer. Didn't have to go very far as I found a Youtube back then of Jay Leno and POR15. Jay painted 2 thick steel rods and when he banged them together no damage, scratches or chips. Since then POR15 has improved things with the Top Coat. In 2014 I only applied the degrease, metal prep and POR15, as I was supposeed to go with another enamel type coating to keep the sun off my POR15. I didn't and the POR15 mostly held up 12 years, but some did peal off. Today I am confident this new coating will last. I used both the degrease and metal prep porocedures followed by both the POR15 rust preventer, and the Top Coat.
