Should I have my car's rear axle area painted with underseal?

@Accy cyclist If you are looking to keep the car it's best done. Yes it's surface rust as these parts are substantial, but if not checked can get worse. It's fairly cosmetic, but it all depends upon how long you want the car. Given it's age, most cars do go a bit crusty on the suspension components. We tend to keep our cars, and I'm always checking stuff, so am usually under the car on a regular basis, so any corrosion get's coated. Yes hammerite will work also, but it's the time it takes. The garage will probably brush off any loose corrosion then spray it with wayoyl underseal (basically black waxoyl). It will keep the parts clear for a few years.

Or you could leave it, especially if you are likely to change the car.

I've left my car overnight in his garage, so the mechanic can underseal it first thing in the morning. I don't get up till 12pm at the earliest, so it's better this way. He's going to wire brush and sand it down then apply Simoniz underseal.

It was picked up on our Fiat Panda. It's finally getting put out to pasture this month.

Still, nearly 100,000 miles on the clock - flew through (mostly) all it's MOTs and has never broken down.

Can't be that bad

We had one like that, 1.2 and was written off twice, but just kept going and went to a dozen different countries. Sold it for the interior in the end but it still was going well.

Don’t use Underseal use Waxoyl. Spray on or brush on, prevents rust and if it gets scratched it ‘creeps’ and fils the gap.

Don't use Waxoyl, use one of the many Lanolin sprays. Inexpensive, requires minimal prep, and is easy peasy to DIY apply.

That's the more recent stuff, and seems a real doddle to do, although you'll smell like a sweatty sheep !

WaxOyl approved by MOD for rust prevention on everything Army, Navy and RAF use. None of the others qualify, sorry.

Lots of shite things, from combat boots to the engines in destroyers, have been approved for use by the MoD. It is in no way a guarantor of quality or performance.

Waxoyl is fine, but the Lanolin stuff is realy easy to apply. Might try this on my next motor.

I've painted most of the suspension on MrsF Qashqai in aquasteel in lockdown. Really good inhibitor. It's now a 10 year old car and the underneath looks spot on.

Nothing wrong with maintenance.
But if this is the same mechanic who at mention of water ingress said the cure was to drill holes in the floorpan; well I'd be looking for another mechanic.

 

[Accy cyclist]

My car is ready to be picked up. He's done the under sealing and fixed my wouldn't open passenger door by putting a new 'opening rod' in. Fifty quid, which isn't bad as I was expecting it to be £100.

Will this underseal keep the water in for your new paddling pool ?

 

[Accy cyclist]

I think I might keep the car now and not get another one in march/April. I usually get another car every two years, usually in those months, but looking at the price of second hand cars maybe I won't. I've looked at 2012 Fiat 500C's. They range from a ridiculous 7.5 grand when low mileage, to £3,900 like mine when high mileage (mine's is just over 80,000. I did fancy a post 2015 Fiat 500C, but I'm not too keen on the new bits like those in your face rear lights and that computerised 'sound system. I Just want a CD player and a radio, not a dangerous when fiddling with touch screen thingy!! 🧐
