Underseal...

Post by Turks » Tue Nov 30, 2010 12:01 pm

I'm just wondering if anyone has treated their X's to an Underseal of any kind? If so, what products and how much to do it?

Just thinking ahead really and want the car to look and keep as good as possible...

Hello Turks,
ive recently undersealed my little run around vw polo at my mates gagrage, just bought myself a brush on tin from halfords and it was good stuff that went on easily and looked neat, but to my knowledge mate (although theres no harm in doing so), this stuff is only generally put onto classic cars. But as i said, theres definatley no harm in treating your X to some

Waxoyl?? Its a real messy job, you need the car up on ramps or over a pit and its , well, amazingly messy......have seen it done on classic Landies etc. and on motorhomes, so why not an X? There is a specialist workshop who does the waxoyl treatment who advertises in Land Rover magazines, but I've thrown all mine out.........

i know a friend who works for landy and he waxoyld the underside of the x for me, again it is very messy, (especially when linked to the air hose of the work shop) but very good for sealing. Ensure car is completeky dry underneath before treating

My mate used Waxoyl on his GTR to preserve the bodywork Link to GTR

He said it was very messy so thats why I thought i'd post to see if anyone had used anything on their X5's...

Its something usually done on Classic cars after they have been restored to stop them rotting but there is no reason why you couldn't do it to your X5 to keep the underside tip top... especially in this weather with all the salt about!

I asked a very reputable contact of mine about this when I had my Porsche. The response I got was as follows. I then gave them a ring about the X5 and they said it would take 3 days and cost about £600. It's a lot so I'm still making my mind up.

The products are either Dinitrol, Bilt+Hamber or Tectyl if you want to buy yourself and have someone apply.

Or find a supplier who uses these products. I can recommend Classic Car Preservation, they Dinitrol.

The place above use Dinitrol (apparently).

Nice one Dan, thanks for the link...

I still haven't had this done. It will be a job for this year alongside getting the bodywork minted with a very good body shop and detailer I know.

Let me know how you get on. I'm considering it for the Spring/Summer and am likely to get a couple of very small imperfections sorted in the meantime. I have to decide whether it's going to be a keeper first but was thinking that, if so, it would be worth doing whilst it's such low milage. One point the guy made was that the grade of steel BMW used pre 2005 was better than after - I don't know if there's any truth in this but nice to know. I think the process involves removing undertrays, cleaning throroughly (and given they speciaise in classic cars I imagine they mean cleaning thoroughly), leaving to dry then treating.

I treated some of underside of mine to waxoyl last year. Trouble is you cant easily get to certain areas particularly top of rear subframe.

Another going over will be another job for later in year.........time permiting.

Alternatively a rust remedy product & satin hammerite are other basic choices.

Dan1502 - Wasnt aware of the products mentioned so will have a look.....thanks :)

My understanding is that they're much less messy than waxoyl. I did have a read up on some of them and think they are also used in marine applications so should be ok.
