Wax coating comes off easily?

I jet wash the jimny every weekend. I always jet the wheel arches as they love to collect the muck.

This week though i noticed that some of the wax coating had come off. Im sure it had wax in these crevices, or perhaps it never had it in these locations after all?





Anyone else noticed this?

The factory coating was only applied strategically. So it probably wasn't coated to start with. Remember to be gentle with the jet washing it can force water past seals and into things that don't react well to being wet.

Intolerance to strong water jets and strong detergents is a typical characteristic of wax coatings. That is their main weakness. Therefore, wax coatings are best suited for cavities and other surfaces where there is no risk of abrasion, strong chemical contact or strong water jets.

There are special underbody wax products (a much thicker and stronger type of wax, sometimes even mixed with bitumen) which have much better resistance, but still not nearly close to being impervious to the effects mentioned above.

An example of such a product is Car System KS-800.

Oh and Andy the coating you picture is actually applied under the colour coat so the fact it is all blue means nothing has come off. Yet.

You guys really know your stuff, which is excellent as a jimby noobie like me. The forum is a gold mine of knowledge, so thanks to you all.

Yes your spot on, because ive only just realised what ive been doing.

When i use snow foam on the bodywork, ive also been foaming the wheel arches, so that makes perfect sense. God damn it!!

We live n learn. Some slower than others :pinch: :whistle:

Im not sure ya know lambert me ol mate, cus some of the wax is half hanging off now, and there is blue under that too.

I'll go have another looksie on me dinn dins break.

Thanks Lambert. Missed ya so i have.
