keeping the rust away

[jpliddy]

hi all is used engine ok to apply to under body of our 900s not everywhere but say painted onto the cill and jackiging points i know its a bit messy but it should dry out like a film type eventually .ive used wax oil in the past but it does tend to crust over then its trading moister in then starting the onset of rust
the underside of my car is still ok but had some welding done a few years ago to rear cills . the battery tray is stating to show signs of rust i try and keep on top of it with wire brush and dinotrol and jenolite , and some copper ease painted on
but need a more better approach if the cars going to out last me !!!!!!
regards jim

Hi Jim

Give it a clean and apply POR 15. Best stuff for keeping rust at bay. Old enine oil will just wash off and it's not very good for the old environment tbh

I've used old engine oil on the underside of a VW Beetle to rejuvenate the waxoyl it had on the underside. All the old Rollers and Bentleys I worked on had a 'one shot' system that sent oil to lubricate all the suspension joints so the whole underside was caked in road grime and oil... the chassis's were always in amazing condition even at 90 years old!

When you come over for the bushes to be fitted I'll take a look and see how bad it is and what the best approach is.

Thanks luke. And thank you all for your comments

Depending on the level of effort, there are many products on the market, lightyears ahead of old engine oil etc, some of the best on the market are made by bilt hamber.

Hello Luke,
Am I correct in thinking that POR 15 is a paint rather than a rust killer?
Does it prevent rust from bleeding through again?
I am constantly having to revisit bodywork areas where I have removed as much rust as possible then treated with rust killer then primed and painted only for the rust to bleed through again.

Hiya Ian

Yeah POR 15 is literally 'paint over rust' what products are you using on it?

Not sure if this is of any interest but i've been working on an idea to derust small areas electrolytically. Still got some final tests to do to prove it works in the "real world" but i know it works in principle as i've used it many times on simgle pieces.

The idea is to rethink electrolytic derusting - instead of bringing the rusty item to the electrobath, bring the electrobath to the rusty item. So far the weather has prevented final testing.

I'll post the details later if it's something useful.

It's excellent stuff Ian but like most things preparation is the key. https://www.youtube.com/watch?v=jQpp...l=HazardSports

I've used on battery tray, gearbox mount and underneath on chassis rail. Gearbox mount is the same today as it was 18 months ago

Struggling to visualise your idea, as the electrolyte bath works in part by the liquid allowing to move the rust particles into suspension away from the part, unless you are thinking of some kind of electrolyte washing/spray device?

Either way, keen to read any new ideas.
