Thanks for the info...I'll leave well enough alone.I didn't get mine rustproofed.
Hyundai uses a roto-dip process, which dips the chassis of the car into the galvanization treatment and rotates it to ensure full coverage of the zinc coating, and ensuring no part of the vehicle goes uncoated. “There’s no way any part of the surface isn’t covered,”
I also read that Hyundai/KIA have their own steel mill which gives them control of the steel they use.
I live in the area where we have winter road salt and liquid ice melt and I might get mine Krown sprayed but will not let them to the engine compartment because of the sensors etc. and I can do certain areas there myself with their spray can stuff...I keep my daily drivers for at least 20 years and every time I did oil changes myself and other things where I had the car jacked up I had the rust inhibitor in cans and sprayed the whole underside just for some added protection...my daily drivers had very little features with sensors to worry about...those cars in those days only had the basic things where as my Venue which is on order is light years ahead of my old daily drivers so I will wait till I get the car and check out everything first before I decide what to do.I have used KROWN on the past 5 vehicles that I have purchased new, 3 of them being Hyundai's. I would not buy a new vehicle without making the 500 mile round trip once a year to St Louis to get my annual KROWN application! 👍👍👍
