Chassis protection

Although I posted the questions below in the Betsy thread, I am going to ask as a "new question" in a separate thread, so here goes..Sorry of this is against normal forum convention.....

I seem to recall reading in a thread on the forum about protecting your chassis with a mix of old engine oil mixed with diesel ...... But am buggered if I can find the thread again despite searching. So....

1. Any experience of doing this?
2. Is there a % formula for the mix or do you just " mix it"
3. If at a later stage you wanted to work on the chassis, weld, waxoyl etc. how hard is it to get the oil/diesel protection off?
Any thoughts on this chaps?...
Cheers

Note - chassis appears to be pretty solid but has had previous repairs. I believe she is currently painted with POR 15 (previous owners receipts show this) but there are areas that require improvement / better protection.

Have used this method for many years,along with extra flaps to keep crud off outriggers ect and oil on.[My 1990 working farm 90 still has original rear crossmember] I add just enough diesel so it sprays easy through my spray gun.
I do it twice a year, only takes 10 mins remembering to squirt inside chassis and not to park on anyone's posh drive for a few days.

Thanks tottot - would be applying by brush initially as I don't have a spray gun etc. As a matter of interest, if you then wanted to "get it off" how difficult is it / would it be to clean up the chassis?

I thought used engine oil turned acidic and slowly ate your chassis. Besides it doesn't seem very sticky. Why not just buy some waxoyl and White spirit to dilute if you want it to go further?

Hi, its not the "going further" bit TBH, but just wanted to know if it is a viable option? My main concern is the ease of cleaning the chassis up at a later stage if and when you want to / need to work on it re welding etc.

There is a lot of debate about using oil and diesel as protection. Personally I think it just attracts dust and dirt and therefore by definition attracts moisture. I much prefer waxoyl or tetroseal. It's tougher and probably more difficult to get off if welding is needed, but if applied before corrosion starts, it should prevent the need for welding. Kind of a reverse catch 22.

as far as spraying goes, the dinitrol black wax can be bought in schutz containers and readily sprays even on relatively cold days.

sealey also do some disposable schutz heads so you can connect to your air line/compressor spray it all on and just chuck the head away afterwards, no farting about cleaning it out

I think what peejaysea is asking is what treatment can later be easily srripped if he wants to go at welding etc....my chassis has been waxoyled twice according to PO records but in the spots where it's peeling its gonna be tricky to get off...but on the flip side it definitely bought some time on the chassis with a lot of what's under the waxoyl being only surface rust.

Correct Jasper74 - but please keep the debate going as more information = better knowledge for us newbies!

Diesel oil mix is easy to remove with preassure washer and detergent. Yes dust does stick to it and becomes part of the coating. Have heard of the acid problem with waist oil but a 25 year old farm land rover with only a few minor patches speaks for it's self. Have only ever used oil from diesel engines.

using oil from a diesel makes sense imho especially if its like my worn old truck, the oil is probably full of diesel already

does it have to be old oil or can one use new?

I have heard that the angle grinder brushes made of twisted wire strands are good at removing old underseal.

This is what I am talking about:

YOU can use new oil , but I am to tight.

Spot on peejaysea the more info the better, interestingly spoke with a mechanic friend if mine this evening and he also recommends the diesel oil mix and has sprayed it on a few vehicles says that's its good because it manages to treacle into all areas of chassis. Sounds good

I used one of these and it seemed to get it off fairly well

Thanks

I am thinking of giving it a go in a small area at first just to see what it is like. Found a reasonable candidate today whilst out trying to get some piccies....

Will see how that pans out and then think about the longer term options.

should imagine that attachment is good at getting surface rust to shiny metal

In fairness chassis looks very clean

btw the oil diesel mix is supposed to be the universal panacea for rusty leaf springs
