Here is my tried and tested method, with photographic evidence to prove that it works!
I wouldn't recommend this method if you're wanting to keep the paint underneath the underseal in-tact. You're likely to remove a lot of it.
You Will Need:
-Hot Air Gun -Scraper -Spray Bottle (something like an empty household cleaner bottle) -White Spirit -Wire Brush Attachment for drill -Electric Drill -Scourer -Kitchen Towel
1) First, you start off by heating the area with the hot air gun and scraping with the scraper to get rid of the worst of the underseal. Don't worry if it all still looks quite messy.
2) Fill your spray bottle with white spirit and spray the area. This softens the remaining layer of underseal.
3) Use the wire brush attachment on the electric drill to go over the area. For tighter or more difficult to reach areas use the wire scourer and your gloved hands to scrape at the area. It'll all look even messier now.
4) Spray the area again with clean white spirit.
5) Simply wipe with kitchen towel and you'll have an underseal free surface!
It definately saved me loads of time compared to just using a hot air gun and scraper and you are left with an absolutely spotless surface.

I prefer soaking old underseal with organic waxes and/or oils. Thus you get rid of the asbestos problem too. I use rust-inhibiting FluidFilm from the U.S. available locally. Biodegradable saw chain oil or just sunflower oil would dissolve tar etc. It needs a few days to do its work. Good luck. Mark
Well, i know Halfords sell white spirit wire brushes and scrapers, iv'e got lots of old clothes (don't tell my tailor) ,but ive never seen elbow grease for sale. Should i try the plumbers ? Seroiusly though,thanks to all

Again an old thread/post but I thought it best to put in here for ease.
I have today been reading up on a company called " before & after " who carryout under car wax oiling/sealing. Ive heard of this company before but never used them. Been on his website today and read all his differing sections etc. He does look like he knows his stuff albeit I found his website delivery shall we say a tad blunt and slightly arrogant.
I was wondering if any fellow P5 owners have used this company/services and what was the result??? are you happy and was a great job done?? The guy appears to have been doing this for many years so I am assuming he knows his stuff or so he should do IMHOP.
Ive heard of some real horror stories where folk have taken their pride and joys to other undersealing/wax oiling outfits and their cars have been sprayed with some concoction and its gone everywhere making a right mess.
Would appreciate any feedback or experiences both good and bad.
If you are able to safely get under your car it is an easy job to do. Cover up the bits you want to keep clean and spray Waxoyl on with a garden sprayer. Waxoyl will liquify any existing underseal and stop any rust. If you remember Ziebart from the 1970's it failed as it dried hard and eventually lifted allowing moisture in. Waxoyl does not dry out unless the car is kept in a very dry environment. If it does just apply another coat or spray with white spirit and it all goes soft again.
You need to do inside the doors as well as all the underside areas and inside the sills. It is a mucky job however carefull you are. I remember removing my chrome sill covers, drilling holes in the metal and then filling with Waxoyl. Unfortunately it was a coldish day and not much Waxoyl came out from under the front mudflap. On the first warm day much of the excess came out and coated the entire side of the car. However 40 plus years later she remains virtually rust free.
If you have it done professionally agree on all the areas to be done.
Each to his own,but I have found the Eureka Fluid film the best anti rust treatment. I keep my vehicles for years so am able to judge the results over a long period. I have left instructions that I am to be buried in the Rover,so will be able to keep an eye on it for eternity. (or until the developers buy the cemetery).
