Lanolin rust spray options please

[RCN]

Just wondering if anyone here has any experience with the lanolin rust sprays. Been thinking of doing under the van and naturally I'm being slammed with every product out there. Lanoguard,Lanoshield, Lanolin LCP,etc,etc.
Any thoughts of what is easy to use, avoid. Some reviews say it needs to be in a pail of hot water, others say it smells like sheep. The Lanoguard guy sells an injector wand for reaching inside the chassis areas which appeals to me.
Cheers

I now use Buzzweld Chassis Guard. Easy to apply and a little goes a long way. You need to touch up areas after about 6 months but as it’s easy to use it’s not been a problem. Previously I had used Waxoyl, both clear and black but I found that it corroded underneath especially on the trailing arms that ended up holed.

I enquired about having Lanoguard done, and was told it needs doing every 12 months.

Sounds tedious, all the manufacturers seem
To still use wax oil based products, my nearly new Audi has it so I’ll stick with that stuff

Lanoguard is very easy to apply and you don't have to be too precious about where you spray. Just avoid your brake disc/pads/shoes. I managed to treat my 6m long Citroen Relay in under an hour - I put the front wheels on the levelling chocks so I could crawl under the van easily.

It's too early to see how good it is as my van is only 4 years old. though modern vans seem to be made from the thinnest steel going.
