I did a chrome delete with plasti dip on my 19 MDX +3 years ago living in the southwest. I hand wash only and the chrome delete has been holding up since. I had to re-spray the front grill after a 2-week summer road-trip in TX. The dip started to come off after my first wash 2 weeks later with the baked on bug guts in the high heat. Zero problems since when I wash the bug guts off 1-2 days later.
