Advice required on Waxoyl
Discussion
Jaguar Steve has mentioned in previous posts to drench the underside with Waxoyl...Anyone here know what Waxoyl product to use and the best way of going about this? Or is there a company in the Hants Berks Surrey area that will do a complete underbody clean and Waxoyl for a reasonable price?
There was a company called Before 'n After who would do the work for you. IIRC the cost was in the region of £400 but a bit of Googling will no doubt find them if they are still going.
Waxoil is not the only rustproofing product you can buy - but it's one I started using decades ago when cars really did rust and it's readily available from Halfords. A company called Bilt Halmber make a product called Dynax S 50 which is supposed to be very good and there's others available too.
It's a easy, but messy job. The car has to be clean underneath and ideally you'll need an air compressor and a paraffin gun to spray the product into all the crevices and box sections, Most of the Waxoil accessories such as the hand pump and application tools you can buy are useless. They wear out and or clog up quickly - a regulated air supply at about 50/75 psi and warm Waxoil thinned by 25% or so with White Spirit is much better, but you'll find the fine mist - which is what you want and not a thick coating - from spraying and drips will get everywhere. Thinned and under pressure you can even get Waxoil inside the doors by just removing the rubber bump stop. There's no need to take the door card off.
One thing you'll notice straight away is how much nicer the ride quality is an almost any older car you treat. That's because lubricating all the suspension components and bushes just eases everything up a bit. You'll find a treated car is so much better to work on too - nuts and bolts come undone much more easily.
Breathing the mist is never a good idea 'tho and don't get even a hint of Waxoil anywhere near the discs and pads...

Before 'n' After are banned from advertising in the Jaguar Enthusiast's club due to member complaints. I didn't know this and got my car done by this company (1 man). He made a vague attempt at undersealing the underneath but didn't brush loose areas off first. Neither of the doors were injected, the sills weren't injected and he didn't underseal behind the front wheel arches (because he didn't take the wheel are liners off). Hence I was totally ripped off. Not a nice feeling but I fully understand and support his ban from the JEC and I think (but am not sure) Jaguar Monthly.
If all you want to do it stop the underside from getting wet & therefore rusty, and you not too concerned about the inner panels and spaces.....
I would recommend just getting the Waxoyl Underseal (black can) from Halfords, and paint it on the underside floor with a brush, you will need ramps, or a good jack at least. But its a cheap alternative to injecting between the skins
Obviously it wont protect the car fully but it will certainly stop the floor from rotting this winter

One of our cars has just been undersealed by Monkfish Performance in Milton Keynes. The underside of the car was stripped of fittings before they started, all seams were injected and sealed, before a final coat over the whole underside.
Not cheap, at £800, but it took 3 days to do, and (IMHO) the most important bits are those you cannot see. I have seen 'One Man and his Brush' quotes of £250 and done inside of a day, but it never lasts.

£800!!! Thats half the price I paid for the car! I can understand spending that sort of money if the car was a lot younger than mine and still had a value...But on mine I think it will have to be a DIY job (hire compressor and spray gun etc)I have a mate with an inspection pit so will use that to get to the underside. I do remember in the past(1985) I had my XJS done locally and paid around £20 for a steam clean to the underside and £80 to have new underseal applied, those were the days, this business is no longer trading which is a shame.Not cheap, at £800, but it took 3 days to do, and (IMHO) the most important bits are those you cannot see.

Thanks for this. I think I will be doing a DIY job on it before the winter sets in.I would recommend just getting the Waxoyl Underseal (black can) from Halfords, and paint it on the underside floor with a brush, you will need ramps, or a good jack at least.

I quite agree. It was more to illustrate that you get what you pay for, and £250 including materials will normally only get you a bloke with a brush and visible areas covered.PaulXJ8 said:

How much? 
£250 for a bloke with a paintbrush to slop some Waxoil about? I don't pay my contractors anywhere near that a day for top quality gloss work in domestic properties.
Including a underneath pressure wash, a thourough wheels off, all cavties and box sections as well as wheelarch shield remove and refit and inside all four doors Waxoil shouldn't take more then a morning to do with the right equipment.
No need for waiting for it to dry either, unlike conventional underseal which forms a impermiable layer Waxoil will adhere to damp surfaces and actually chases excess moisture off.

If you are going to do a proper job of cleaning there is quite a bit of prep work in protecting electrics and other components. Just like with painting the more surface preparation you do the better the end result you will get.
