rustproofing

(1/5) > >>

land-def-90:
had a look under the 90 today and decided it needed rustproofing, choices are waxoyl which i cant really afford at this moment or spraying the underside with used engine oil at a fraction of the price would welcome any comments on subject

spinkster:
whilst waste oil will give you some protection (and its best mixed with some deisel and shoved up the inside too to help it creep more) it isnt ideal for 2 reasons....
1. it wont last anywhere near as long as waxoyl(or similar)
2. you wont be popular with anyone who's house you park outside, and you may possibly get your collar felt if some "greenie" see's what your doing and reports you as its strictly illegal as waste oil should allways be disposed of in a controlled environment (and bunging it all over your chassis is technically disposing of it)

extreme90:
waxoil is rubbish and so is underseal......soon as mud hits it it sticks and wont come off so it makes it look like your chassis is rusted

spend a bit of time onit and make a proper job

wire brush the chassis all down, spray it with a etch primer and then spray with a gloss enamel black paint and itll look better than new and the mud will flake off with a hose pipe

its what i do to mine and is well worth the effort

all for about 40 quid

It may look like your chassis is rusted but it isn't actually which is the main thing surely??

Personal opinion I suppose but I have been using Waxoil & Finigans underseal on my LR's for over 20-years (likewise my father used it on his S11 for 15-years) and we both swear by it as it is very effective at keeping rust at bay.
I did my current 90 about 7-years ago and apart from some slight touching up now and again the coating is in excelent condition and if you scrape the coating off and look underneath you can see the metal is in perfect condition.
The bittumin type underseals are not very good as when they have dried out water can get in behind and rot the chassis (like on the old MOD S111's) but Finigans underseal remains flexible even after many years.


The trouble with hard coatings is that they are prone to chipping.
