Pressure Washing Chassis, outriggers, Diff, wishbones etc
Discussion
The cars up on axle stands and I'm starting to clean off all the old waxoil, powder coating and road gunk before I can get on with wire brushing and rust protection.
At the minute I'm doing it by hand with a brush and soapy water. I was wondering if I'm going to damage anything by taking the pressure washer to it? Are there any areas I need to avoid or be careful with sensors etc?

Just done mine with a pressure washer.
Did that first to get the easy bits off then attacked it with a wire brush, scrapper and then loads of de-greaser.

Did you dismantle your wishbones? It looks like a complete pain in the bum but probably the best way to do the job properly. Did that first to get the easy bits off then attacked it with a wire brush, scrapper and then loads of de-greaser.

Ive done two of these chassis now and dismantling the wishbones is a must. While your at that may aswell do the bushes! Whilst doing this may aswell change the ball joints, then brake hoses.............
Basicly it can turn into a big job.
Taking the wishbones of is easy enough to be fair, although as long as they are in good condition anyway it wouldnt be to hard to work with them on the car.

Thats what I'm worried about! I know how anal I can get about these sorts of jobs once I start doing them and before you know it all the little things you've replaced start adding up. The wishbones are pretty much nearly new, powder coating is still all intact and no signs of rust. I'm guessing they have been replaced recently by the previous owner. I'll have to check the receipts.

Degreaser seems to do the job...the best stuff I have found was at the pound shop! Guess what - it was only £1! Its a orange aerosol - don't know the brand...probably not one but it works a treat..maybe not as good as Gunk but Gunk costs £5 a tin....
Leaving my wishbones on the car...managing quite well so far. Painted the suspension...sterring arm...ARB...chassis etc. Agree that to do a thorough job the suspension should be dismantled by mine wasnt that bad and didnt warant it.
Never tried a pressure washer on old waxoyl...?
How are you all getting on? Any nightmares?
I am going to start mine shortly (never done it before, just figure that I will be thorough *because* it's my car!) any additional tips would be much appreciated.
So far I have a shopping list of: Wire brushes, scraper, de-greaser, chassis paint, waxoyl (or similar, not decided yet).
Did think of getting some wire brush attachments for a drill. Good idea? Or could that be a potential struggle?

well as an update I tried degreaser at the weekend. Sprayed it on left it 3 times longer than recommended then pressure washed it. It did get quite a bit of the waxoil off, though i think that was more down to the pressure washer than the degreaser! I've done some digging and the solvent that waxoil uses is white spirit. I've just got 4 litres of the stuff so I'll be putting this on with a scrubbing brush on sat to see if this will get it off.
I've got several wirebrush drill attachments but I thought it would be better to get the waxoil off first. I tried them on the outriggers and they do work but the best I found was a wire cup type attachment for an angle grinder. Straight through the powder coating and rust to bare metal with little effort! obviously this is only useful for easily accessible areas but its still worth getting hold of one!
One pointer I will give you! If you lie under your car and pressure wash it you are going to get wet, very f
king wet! Other than that I'm too early into the process to offer you any really pointers that havent already been covered in other similar threads. If I come across any good ideas I'll put them on here.
One other thing though, dont use waxoil! If you want decent protection use either por15 or rust bullet. I've done a st load of research, not just on here, and they both offer really good rust prevention. I'm going with rust bullet as it requires less preperation than por15, i.e. it goes over existing powdercoating and new metal where por15 can struggle to adhear to these.

ok im going to be doing this soon and want some pointers too.
how do you apply this rust bullet or por15? brush/aerosol/airgun? and where do you get it from? price and size/litre
is anyone painting the chasis in rust proofong stuff first? like zinc paint, hammerite kurust etc?
i can see a patch of rust on the chasis where the manifolds pass or are above and i understand this is a common rotting point. mine hasn't rotten but can i protect it more by welding a patch of extra metal on top? what have others done to over protect the common rotting areas such as this and the outriggers in the wheels arch

I did mine the other year. Went over everything with white spirit using a brush and raggs. Then applied a rust proofer, and finished off with white Hammerite. It looks ok, but i wish i had a lift to put it up on to make sure i had'nt missed anything. Did the best i could, and it took about a week. It does feel good knowing that it's as good underneath as it is on top. I dont take my baby out in the rain if i can help it, and would never take it out while there is salt on the roads, so it should last for some time to come.
