Under-sealing and rust proofing

[lee_erm]

I plan to spend a couple of days under-sealing and adding cavity wax in to various orifices of my E86 next week. In the past I've used Hammerites Waxoyl and Underseal for this job. Can anyone recommend any more modern products for this job though?

I won't have access to a compressor/air line so I'll be using aerosols.

Thanks

I have no connection with the company. I have used these products with success for many years.
Preparation and careful implementation is the key to it.
Do not trap water.
If you're in the UK and do not have drying facilities, it may be best to wait for a prolonged period of appropriate weather.

another vote for Lanoguard - easy DIY job
its an annual job but is not messy like waxoyl - Ive done my Land Rover the last few years and will be doing my Z over the winter layup - if it works on the Land Rover will be no brainer on the Z.

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.
