undersealing

Post by telreyn » Sat Mar 21, 2009 9:02 pm

After four months in my garage with sub-zero temps converting my 2001 tin top to a campervan which was registered in Feb. 09 and went through with out any problems,it must be time to look at having under sealing done.
Living in Southampton there about three companies to choose from one at Ruby,one at Poole,one at Hayward's Heath.
Ruby is to far to travel,Poole sorry but did not like the look of his workshop and the biggest problem was the price £625 (what.)
Anyhoo I phoned underbodyprotection at Hayward's Heath and had a chat and found Mick to be very helpful so booked my Bongo in to have job carry out.
His workshop is set out in country very nice area also is very tidy.
Work was completed over a two days and Mick has made a first class job of it very pleased.
So if your thinking of having under seal done then I highly recommend him,another important thing is he uses Dinitrol
and not Waxoyl cost between £400-450 depending condition of vehicle.

wow, is that how much undersealing(is waxoiling the same thing?) costs?

so If I were to ask a seller if the van hed been undersealed and they were to reply "no, not yet but I will get it done and paid for in with the price" should I be wary? Is it easy to tell just by looking if it has been undersealed?

thnaks :)

There is a big difference in the process between a £100.00 underseal and a £430.00 underseal. The later is normally used on classic cars and there are only about half a dozen places in the country where you can get this process done. The one I used in the north of England is near Manchester Airport. http://www.chassisclean.co.uk/

Hi telreyn
Dinitrol products are good, as long as they are applied properly....and they've been around a lot longer than waxoyl, although i remember waxoyl kicking off in the 60s. If you are looking at keeping your camper for a good number of years, you might look at some of Dinitrol's military spec. coatings, as some of their products far exceed any waxy underbody sealants, and I really like their cavity wax. The aerosol cavity wax with the extension probe is excellent for "topping up" the cavity coatings...I use it to save getting the compressor and all the kit going (laziness)

I had my Bongo undersealed by Rustbusters last year. You pay a lot but get a Rolls Royce job.

It is a horrible price, but it is the full classic car underseal, with the panels and tailgate injected with white waxoyl. The car is also treated before being undersealed, so that rust is not left underneath the coating.

The premises are scruffy, but so are a lot of specialists. You are paying for skill not decor. I was very pleased. No breathers blocked or seal in the wrong places.

One winter is too soon to judge, but so far not a mark.

I owned a Range Rover that had had this done by a previous owner. Despite it being used as a Range Rover should be. Up to the axels in Hampshire mud, it remained in really good condition. It looked immaculate at eleven years old when I bought it and still looked good at sixteen years old when I sold it. No tail gate rust and no spots on the wheel arches.

An untreated Discovery I also owned suffered dreadful corrosion including a collapsed floor and usually needed a weld for a MOT.

Since I keep cars for years and the Bongo was virtualy rust free when I bought it for me it made sense.

What this thread serves to warn us of is that (a) there's a huge range of prices for this job, and (b) any equally wide range of thoroughness. There, how helpful is that? :)

Sluggy, I would certainly be wary of a thrown-in undersealing if offered as an inducement. You'd need to have it confirmed beforehand just what the job entails. I dare say some reputable importers will provide a good service here, as they want the cars to last - along with their reputations. With the Bongo (well, any vehicle really), the inner panels really should be treated too, as rust almost invariably eats from the inside out.

Best to go with recommendations. Didn't I read that Wheelquick offer this service, with a range of options (all of which seemed very good value)? That's what you ideally want - a recommended garage at a reasonable price (yep - if you ever want someone to state the bleedin' obvious... :( )

When I was looking for a Bongo for my niece, one of the questions I asked was whether it was undersealed. With the one we finally bought, the dealer offered to do this at no additional cost. Well, you gotta laugh at the job... Someone must have spent all of two minutes walking around the car, bent double, firing black underseal under the car at random. Under the car looked like the back of a Fresian cow.

Ironically, when I was searching for a Bongo, my ideal (which I found) was a Bongo that had not been undersealed but that was looking good underneath. I then spent £400 with ChassisClean for a top notch job - worth every penny (unlike ordinary waxoyl, which ought to be checked and reapplied every year in high abrasion areas, the job is for life although they recommend a health check every 3 years). All that did not however prevent me from discovering a small area where the n/s cill joins the front cross member that had rusted right through. It reminded me that the treatment cannot fix what has gone before, prbably (in this case) water running down in the area of the front door pillar and getting inside a box section. Easily fixed with a welded plate (thanx to Wheelquick) but I almos wondered whether it would be best leaving a drain hole in the plate :roll:

lookiing at having ours re done, was done when we fisrt got it just over 2 years ago but think it would be worth doing again as we are keeping van for a while. Chassis clean is not to far from us look good so might try them.

The normal Chassis clean process takes three days. I hope that you have somewhere to stay nearby or a second car to take you home al & chris. That said I was lucky that I have a sister who lives near Wigan. Rhod from Argyll had to stay in a B&B but they did a quick job for him at his request which took less than three days..

ChassisClean used to have a courtesy car (nothing fancy but it works) they let you use while yours id being done - worth checking. One other thought. If its been done before, then really all the cavity filling work (provided it was done properly) shouldn't need redoing. Also, I don't know what view ChassisClean will have about putting their work over old work. It's worth discussing with them (the are really good guys - no hassle at all) what the best approach might be. It could be they'll say bring it over and we'll only do what's needed, and the price could be rather less than a full job. 8)
