Trying out Lanoguard

[APS]

[posting this in the Aygo forum even though it isn't really model specific - Admin feel free to move as you see fit]

I know many have discussed and considered using Lanoguard so I thought I'd give it a go on our 2014 2nd gen and share the process and outcome.

The process is pretty straightforward:

1. Get the car in the air, and the wheels off
   
2. Pressure wash everything on the underside
3. Poke, scrape, and wire brush off any loose rust.
4. Let the car dry (best done by putting wheels back on, lower, and take for a spin)
5. Apply the thick grease version of Lanoguard to the rustiest areas, nuts, bolts, seam welds. 
   1. The grease needs heating to turn it liquid so you can brush it on. This is a bit of a PITA at this time of the year since the grease hardens as soon as you brush it on to cold metal. Likewise, the grease in the tub starts solidifying pretty quickly at these temperatures (about 7˚C). Probably better to do this when it's a bit warmer outside.
6. Spray in cavities using the spray wand/lance
   1. I found that the lance doesn't produce a mist but essentially sprays mostly in two, opposite directions. This means you need to spray while rotating and going back and forth. Seems like you waste a bit of fluid doing this.
7. Finally, spray everything with the thinner Lanoguard fluid. Very easy. 
   1. Avoiding brake discs and any engine belts. Exhaust is OK. It just evaporates I found out.

You can see the thick grease around the suspension arm bolt head, and brake unions. The brake unions had grease on them previously.

The lanolin forms a waxy coating that works on the principle of soaking the substrate and repelling moisture. You know how old cars never rusted around the engine and gearbox where it leaked and constantly soaked the surrounding bodywork in oil - this is like a deliberate version of that. Just stickier and all over the place. The process is a little messy. Particularly when you inject cavities since it starts dripping out of various places. Including on top of you. In the end, both the car and you will smell like a sheep farm - for that rustic country side feeling. 

Now the car needs to stand for a few days. We'll have to see how it fares over the course of a year.

Fabulous tutorial, APS.....Many, many thanks.

I had my little fella undersealed a good few years ago but I was wondering about a top-up with this stuff.....I think that you might have convinced me! 

Many thanks and all the best.
