I have mixed thoughts on this.There is many unpainted spots under the caliber.Looks to be primed only.I have a 95 Ford truck that was undercoated. And its badly rusted now under the under coating. So what do you all think?
It depends on the job... undercoating on a fully assembled car will likely promote rust rather then prevent. There is no way you can fully prep every nook and cranny and get spray to cover every bit to lock out moisture. When moisture finds its way between the undercoating and the metal/paint it will rot away fairly quickly. I thought about it with my caliber as well but decided against it... i rather keep an eye on it and try and wash salt off.
100% agreement. I have had the "luxury" to see many undercarriages of newer cars and every one that is about 8-12 years old that was rustproofed is far worse off. Just keeping the car moving and not letting it sit in a damp closed garage all the time helps too.
Moisture will seek and destroy EVERYTHING in it's path.
