Wax/polish

[NewC5dude]

Hoping to get the C5 washed tomorrow and give her a good clean and shine, any waxs recommended or any i should not use. Looking to clean under the bonnet too any help is appreciated

[mickthemaverick]

I wash my C5 with snowfoam, then turtle wax and rain-x on the glass. Under the bonnet its multi surface kitchen cleaner for the metal and WD40 for the plastic and rubber. Good luck

Thanks, i only have a cheap triple wash stuff just now. And triple wash wax. I will get snow foam tomorrow. Hopefully it will come up nice

My priority has been for wax on the underside.
Last Rover (P6B V8), BX, and now XM all got thorough underside and cavity waxing, and all remained totally rust-free - really important for hydraulic pipework!

Current kit is now a Sealey SG18 wax injector/spray gun, which uses an air-line (to pressurise the container) and a cavity wax of choice...

4CR cavity wax...

less expensive and far more durable than waxoyl.
Other brands available

I was just away to ask about under sealing it. All my cars have had under seal on them. I just did it by hand on the drive way haha (old skool way)

[white exec]

That's what I used to do, using cheap plant-spray bottles, and warmed waxoyl, with an added long nylon pipe for the sills and box sections. A miserable and lengthy job. The Sealey gun just makes the job quicker, cleaner and less wasteful.

Well wont be today, pouring of rain already . Is there any place i cant under seal on these C5's? I would be doing sub frames front and back and sills any place i have missed?

For polish, this takes some beating

What ever wax you use.....CLAY Bar it first. (or go cheep and use "Plumbers Putty")

[Gammyleg]

Try and use a product that contains no salt, even though salt is a cheap powerful cleaner it is very good at starting corrosion.
Its difficult to get a product that doesn't contain salt but they do exist.
Silkolene car cleaner doesn't contain salt and Muc-off contains a type of salt that is not corrosive. ( trade secret)

On the subject of wax , use a good carnauba wax with no polish such as simoniz (polish contains an abrasive which thins your paint).
If you dont have faded paint don't use a polish.
Rinse your car thoroughly to get rid of grit first.

If You get your engine clean use a dressing with silicon such as gt85 which will make it much much easier to clean next time and stops dirt sticking.
Dont use a pressure washer as it can force water in to electrics and bearings.
Its slower to use gentle methods but its better in the long run.

I never use silicon, it dries out rubber very badly as it breaks down the plasticisers making a brittle layer that deepens as it cracks.

Valid point Alasdair
Avoid contact with any rubber
I used to use dressings with silicon on my motorbike but I was carefull not to get it near the tyres or rubber components.
