Most cars start to show signs of corrosion/deterioration on underside fairly quickly especially when salt is used on roads.

I have used Lanoguard in past as seems to go on easily and does not set hard, but does need periodic reapplication.

It is also quite expensive, around £100, but can be a diy job and also used in marine applications to protect parts.

I have ordered some Fluid Film to try, which is more common in US and is also lanolin based.

Whilst only considered cosmetic, I do like to preserve the newer appearance of suspension and underside.

Would be interested in others experience.

Have a look at Bilt Hamber products.

My strategy involves only driving it in the summer and leaving it tucked in the garage away from bird strike, hard water etching etc when not in use but I’ve heard good things about Bilt Hamber too 👍🏻
 
I was looking at Lanoguard but Bilt Hamber also have a 5 litre which is a bit cheaper but how is it applied?

Only used Dynax from an aerosol - simple application (in fairness, I've only used it on bikes)
From their website

Aerosol Dynax-UB:
Large 750ml aerosol, comes with standard spray head and straw attachment to get into nooks, produces professional ‘stippled’ finish.

1ltr Pail Dynax-UB:
Viscous formulation for application with brush or roller.

5ltr Jerry Can Dynax-UB:
Formulation for use with compressor and suitable spray equipment.
 
Have used Lanoguard on my GRY.
I initially bought the full kit including the hand spray bottle - but have never used that. I just use the gun that fits into the container of lanoguard. I also got the grease and did all of the nuts and sub frame. An hour later I then sprayed the whole underneith very thoroughly remembering to cover the bits that needed covering.
I used just under 1 litre for the whole spray. The rest I sprayed it again in it's second year in the Autumn and still had enough left to do my AygoX so 3 sprays from 2L.
The replacement 2L tub is £57 so I will get that soon for this Autumn and next years spray + the Aygo again so not too expensive overall.
My car has done 6K and looks like new underneith and yes it has been used when salt on the road but I rince the underneith. I recon I could do it every 2nd year and it would be fine. I think brushing the warm grease on first is probably the important bit. Not sure how long that will last but I did put it on thick.
I believe all products are good and will do the job and if done and kept up with I can't see why a car shouldn't last many decades (30 years at least) if rinsed each spring and all chips touched up. My RAV4 and Celica were 12 & 13 years old without a mark and very light surface rust and were untreated. What would they have been like treated?

I wanted to try some Fluid Film so bought a spray can to try.

It doesnt dry like Lanoguard and stays wet.

There may be some areas that this would be OK, but think I will go for Lanoguard.
