Kennyh Posted April 7, 2019 Share Posted April 7, 2019 Hi all I’d welcome peoples views on whether it is wise to underseal a new Motorhome? I’ve previously had new cars, that I intend to keep for many years, treated at a specialist under sealer with Dinitrol - under/in the chassis, in the doors etc - all with a view to extending life before any possible corrosion sets in. I’m considering doing the same with my recent purchase, based on the Ford Transit Mk8 chassis. Any thoughts on whether that would be a good return on my investment?

EJB Posted April 7, 2019 Share Posted April 7, 2019 If you are keeping it for 20+ years I would say chassis treatment will give you peace of mind. The MH body is a different matter and it's possible to seal damp in in some circumstances. As a second hand sales point I don't believe it's worth anything.

blaven Posted April 7, 2019 Share Posted April 7, 2019 If it's an ordinary commercial Ford chassis and you want to keep it for as long as possible I would definitely invest in rust prevention. You've got to remember that a commercial vehicle is pretty much only expected to survive 3-4 years by which time it'll have clocked up tens, maybe hundreds of thousands of miles. The engine and running gear will be far more robust than the chassis and body. Rust and oxidation occurs in our climate all year round, and during any periods of non-use.

Kennyh Posted April 10, 2019 Author Share Posted April 10, 2019 I’ve now arranged for my Motorhome to be under-sealed. £800 - not particularly cheap, however I am planning on keeping the Motorhome for a good number of years - so I believe it will be a good investment (many years from now).

Billggski Posted April 10, 2019 Share Posted April 10, 2019 Just a few comments. The Fiat body is galvanised so doesn't need any extra treatment. The Ford body has a 12 year "anti-perforation" warranty, which I guess would be voided (bizarrely) by putting an extra coat on it. Waxoyl and similar treatments give off fumes for quite some time and it is recommended not to sleep in the moho until it has dispersed. I used to do it myself when I was more flexible. Using a kit like this. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F153259216948 My local garage did my land rover for £150.

Anti-perforation warranty does not cover chassis or load platform, it only covers panels - even then it does not cover due to stone chips. The underside of my Motorhome on a Transit Chasis (I’m sure like many) has lots of galvanised components, but they will start to rust at some point. Using underseal will improve the lifespan of those components as well as inside the chassis frame. I agree it is not cheap - but there is a lot of time /effort spent in the prep work for underseal to be applied as well as cost of Dinitrol. I suppose it’s like insurance - I generally take out GAP insurance - will I ever get that money back - most likely not - but if the s**t hits the fan then I know I’ll get a new vehicle. Likewise, I may not need it - but after seeing the state of numerous Transits and other vans on the road - I think it may prove useful in the long run (and I do intend keeping the van for probably 10yrs or more (retirement coming soon :-) Link to comment Share on other sites More sharing options...
Charles Posted April 11, 2019 Share Posted April 11, 2019 I spray on white lithium grease, you can buy multiple can packs on ebay. It doesn't peel off in 2 years like waxoyl. I know it lasts at least 12 years from personal experience. Link to comment Share on other sites More sharing options...
Mickt Posted April 11, 2019 Share Posted April 11, 2019 I too have used lithium grease works well Link to comment Share on other sites More sharing options...

George Collings Posted April 12, 2019 Share Posted April 12, 2019 My1997 nearly 100.000 miles VWLt ( basically a Sprinter with a VW engine).based van stands out in all weathers. I bought it in 2008 and for the first three years spayed the underside with Waxoyle until a good coating built up inside and outside the box sections.There is no significant corrosion anywhere . It means you get filthy working underneath as it grabs road dirt. Link to comment Share on other sites More sharing options...
monique.hubrechtsgm Posted April 12, 2019 Share Posted April 12, 2019 I think that you are talking about a anti rust paint looking galvanised. Dinitrol was and still is a wonderfull product. It doe not peel off if instructions followed about the substrate. Only AL-Ko has a zinc bath chassis. Link to comment Share on other sites More sharing options...
