Hi all. I am thinking of having the underside of my 2010 Puck L treated with Waxoyl, both the steel chassis (inside and outside box) and the caravan floor. Any comments, or advice welcome. There seems to be a fairly well thought of company down in Dorset (Rust busters) who specialise doing motorhomes and caravans. Just wondering if anyone has any knowledge to pass on that I should know please. Many thanks.

I am sure it's worth doing, I was going to do my Puck a few years ago but I changed it out for a Familia with a galvanised chassis, however I did waxoyl my old MG and I remember the constant pong of paraffin and oily wax marks on my drive where it had dripped out on a hot summers day..

....... was it a good thing or a bad thing then?!!....

I don't know much about this about I would have thought it was only worth doing to a new vehicle or one that had been treated already. Isn't there a danger of sealing corrosion in?

Its been suggested to me that any rust will be sealed by the treatment, and so 'halted'. I only know what has been told to me by people/companies who do it ..... would be nice to hear from anyone with personal experience. I am a bit ignorant and don't want to do it and then regret it .... if you know what I mean. Unfortunately I don't have a galvanized chassis. They also suggest it is good at preserving the caravan floor.

Interesting ...... thank you. Sounds like I would need a clothes peg on my nose if I took the van on warmer travels!!

what do you treat the underneath of the wooden floor with then ?

Hymer do use a special preservative spray. Have a word with Jandi caravans. They will advise you what it is and probably supply it for you.....

I Waxoil all the lower frame that I think needs it every year. Who knows if it is doing any good? Better than doing nothing? No smell inside the 'van. (In any event, I like it's smell.)

(Before you start, warm the tin in a basin of boiling water. Shake the tin to hear/feel that the contents are thin and runny.)

So.... correct me if I am wrong .... I am thinking from what is being said, that I could have what is seen of the chassis frame underneath (inside the box and on the outside surface... including over the top of any powder coating that is good and intact?) treated with waxoyl, but maybe not the wood floor ....... stick to the Hymer product for this? ( is waxoyl therefore harmful to the floor?)
. The chap down in Dorset /Rustbusters seemed to suggest the floor would be ok to treat with Waxoyl too?.....and that it would be a good thing.....however, I don't want to do anything silly ; I know I can get hold of the Hymer stuff for the floor if this is considered best? (through Lowdham Leisure world ). Just trying to look after it in the best way possible, bearing in mind there has been some rusting ....

Thanks everyone for your posts, I really appreciate it. Just a shame these chassis weren't galvanized.

I'm a long standing 'Waxoyl" fan, having used it liberaly on many 'rust prone' cars I've owned, including my 30 year old Citroen 2CV (many of which required new chassis following failure at their first 3 year MOT )

Coating the outside surfaces is only part of the treatment, it is (IMHO) essential to high pressure inject into to hollow,or, box sections, to protect against the unseen condensation induced internal rust !

I would not Waxoyl directly over rust if it can be avoided (though it may help) best to clean up and paint with chassis paint and then Waxoyl.

With my Eriba I've painted only the box sections and steel areas - I believe it is NOT a good idea to coat the floor areas with Waxoyl. Again try to inject inside the box sections. Waxoyl won't spray if thick and cold - it's very difficult to keep warm enough to spray succcessfuly, best to thin with turps type thinners for box sections and then temporally block up the filler holes until the liquid evaporates and thickens ! Then remove the 'plugs' to allow the sections to breathe. In a car I run it around for a while to slop the 'liguid' around to cover as much inside as possible (may not be practical in an Eriba).

Be prepared for the strong smell of Waxoyl but it will go !

Hope this helps :)
