the stuff you cannot see, ie the subframe and a few other spots.

Where the chassis rails curve down from the engine bay, and under the floor of the car seems to be a favourite place.

Do you mean the crossmember behind the bumper?

What bits need removing from under the car for a good undersealing? Does the diff and fuel tank need to come out or can you spare behind with the tank in situ?

Look back on my old posts I have a pic of the chassis frame issues.

Also behind the bumper the chassis rails under the lights rust. Not to bad from a repair point as its easy to get to.

Under the bonnet on the near side, about halve way up hidden under the sound proofing, I found a spot about 3/4" in diameter frown

As you open the bonnet at the front of it on the inside of it , worth taking bumper off and doing front subframe , plus where the jacking points are , it's always worth doing front and rear arches , I reseal car about once a year does not take long , when you go for a mot then ask to have a look , the bonnet bit is first bit to check

If you follow bs a bit in the bonnet. Cut it out and put a vent there!!!

Worst place is probably on the top of the front chassis leg where the front cradle bolt comes through
Usually o/s/f , downpipes quite close there , may cause it to sweat & corrode

Anyone having any sort of wax oil or dinitrol etc it counts most in box sections & seems

Putting your head underneath & seeing it looks nice & covered means nowt you never see a panel rotting from the centre out

And here's a link explaining the different types of rust proofing.

http://www.dinitrol.co.uk/Products/RustPreventionW...


Don't use the black stuff that covers and hides what lurking under it. The guys on the classic mini forum tell me, it's scary what rust proofing hides.

I'm thinking of using this type of product for a number of reasons

It's clear ( so you can see any issues araising

It'll help alot when they put so much salt on the roads in winter ( Northwest they use far to much on the roads )

Thanks everyone! I wasn't expecting major component rot, i was expecting you all to talk about boot lids and rear arches, like on all my previous BMW's. haha

Rear arches can become an issue but only if not sealed up. Normally a stone chip. There a nasty design to repair if caught late.

By the box section are in some areas. 3 layers of metal. So inside it rusts out and it looks clean outside.

Difficult to see what traditional rustproofing is likely to achieve on a car which has been driven all it's life through winters. All the nooks and crannies will be full of road debris and harbour moisture. Weak areas will have started to rust. Any treatment will need to thoroughly clean these which would be very labour intensive. No professional could do the work for sensible money.

If the car has not seen winters then post treatment now could be effective.

Body on mine has stood up well and I have periodically squirted WD40 into orifices in the chassis rails, bonnet etc. Suspension components have suffered a bit which I have wax oiled, but ultimately these parts are replaceable.
