Haha I replied to the wrong thread


Replied to a 2021 post after reading yours lol what a moron anyway here:
I got my 2007 E86 60k miles up on a ramp a few months ago and did a full treatment underneath.
Remove the trays and washed it all first.
Let it dry then painted on Kurust to any problem areas (mine was practically none but I went over absolutely any surface rust I could see.
Then let it turn black or dry, then lanoguard spray it all and stuff the lanoguard grease in the arch lips and anywhere else you want.
Pretty easy job.
Plus it's clear so you can see any problem areas later.
If I was selling this in the future there's no worry about not seeing what's underneath the protection because it's all visible.
Plus there's no rust anyway so I'm quite lucky with this car but I'll just jack it up every year and refresh.
I don't drive it in the wet or winter and the previous owners were just at anal about it (clearly) think one of them actually stores it in a car storage hanger every winter lol.
Lanoguard though is great I've used it on 5 of my cars now.
