all,Chassis Strip
Discussion
Hi all,
I have a 5 days off and wanted to strip back the chassis (body on) to treat it. My question is - how many hours will this take and what is the best technique (wire brush or electric drill with sutiable attachement). I do not want to start and not finish before I am away again.
Cheers

Hi,
I work on my chassis in the evenings during the winter and have a reasonable appreciation of how long this takes. To do an outrigger (by which I mean the pole that runs along the side of the car (2.5m long-ish) and the one beam that is about 3ft long that links the outrigger to the chassis beams around the transmission tunnel). Seven hours on the first day followed by 1 hr a day for at least 3 days.
This breaks down as:
1hr to clean old wayoyl off chassis with white spirit (you could use a steamer)
4hrs to use wire brush on a drill or dremmel to remove surface rust from underside of outriggers and then use sand paper on the top surface of the riggers - thread it through gap between body and chassis tub and then work it back and forth. You will send alot of time on less accessible areas e.g. where body mounting plates limit access to top of outrigger. This is the area that most needs treating.
1hr to reclean chassis with white spirit to ensure all grease and dust removed.
This step is optional but you could apply Bilt hambers deox-gel and leave it overnight to get rid of all little bits of rust remaining - then wash off after 24hrs.
1hr to apply kurust.
Once kurust is dry: 1hrs to apply first coat of paint.
Once first coat dry: 1hrs to apply second coat of paint.
Apply third coat of paint - depending on the brand of paint you are using this may not be required. In the past I've used two coats of hammerite primer followed by two coats of hammerite paint and rust spots have started appearing after just one year!
I now use Epoxy mastic from rustbuster - three coats. I'II let you know if this is any better once its been on the car a while.
1 hr to apply waxoyl when paint is dry. For Epoxy mastic the waxoyl can go on the day after but with hammerite you have to wait a few weeks for the paint to harden properly.
Ultimately the amount of time spent will depend on the quality of job you are after.

It also depends on what you are hoping to achieve and what condition the Chassis is in now...
if its in good condition with little rust and all you want to do is flash it over, then you should be OK with 5 days to remove the old Waxoyl with rags and white spirit, dry it off wire brush the corroded bits and hammerite again but you should not apply waxoyl again until the Hammerite has fully hardened.
However if its more likely that there is significant corrosion you will need a lot longer then 5 days to do a decent job (it took me five months working one or two days each weekend sometimes for 12 hours at a time.)
I used as main tools, a short knife blade, wire brushes, emery tape, hacksaw blades and a thousand litres of elbow grease...
You will need to dismantle some bits to gain full access and removing the rust is a tough and slow job.
If your Chassis is rough and time is a constraint I would spend three days cleaning up the Outriggers (and if time allows, the trailing arms)as best you can allowing 2 days for repainting etc...
it will be interesting to see how you get on...
good luck

Mine took a few months with the body on weekends and the odd evening.
You need to get motivated when its cold - winters the best time to get the car up on stands but you need to get a heater on to dry the paint.
Worth wile once its completed - knowing the jobs done to your own standard and knowing the condition. Ok you can't see all the chassis but it's better than just leaving it to rot away.
