What Can I Spray On To Inhibit Rust Formation

What can I spray on to inhibit rust formation underneath the boot floor area? Hammerite seems useless.

dont you need to get rid of the rust first before painting over it ?

 

i use redoxide

[Anton green 12 1 Cars]

Assuming I sand off any of the light surface rust which is starting to form in small patches, will redoxide permanantly inhibit rust formation, or is it not durable? If it is good I may strip back the coating under there and do the whole thing.

 

I haven't used red oxide before, is it available in aerosol?

You will need to seal the red oxide with a gloss of some type as red oxide will let moisture in over time.

I use a coating of grease and oil

Wax oil has a rust inhibitor in it. red oxide is available from most hardware shops in areosol or brush applications as is waxoyl. sand as much of the loose rust away as you can Jenolite is another good inhibitor. you can paint a primer or colour over it. hamerites more of a sealer after the jobs primed. Beware that unpainted red oxide will eventually absorb moisture. but should stop the rust for a very very long time.

We used to use it on the chassis for the forestry commisions lorries which used to spend alot of time caked in muck.

EDIT: Ha Sutol &mickie beat me to it. but you have all the answers now

its available in aerosol and a tin, im not sure if sand paper will get rid of all the rust, you may need to use an engle grinder with a wire brush on it or rust remover first but it seems to be doing a good job for me..

 

someone with more experience with rust might think differently tho..

i use THIS for bare rusty metal after i've got as much of the rust off as possible. then i put a good layer of THIS on top . it dries to quite a rubbery wax which unlike waxoyl will take a good battering under the wheel arches etc.

 

and for inside doors, sills i use THIS.

if you get it nice and hot its as thin as hot oil, and i find it great for inside the sills,doors, panels. it dries to quite a soft wax.

 

i used to be a firm believer in waxoyl and kurust and the non trade jenolite etc but i've been converted.

 

you'll never get rid of the rust , you will on only slow it down , especially on a 205, because they always rust on seams and around spot welds which are impossible to treat

Your best off brush painting it on mate. It goes on much thicker than spraying so it wil last longer.

Do you mean boot floor underside?

[Anton green 12 1 Cars]

I do. And all around the box sections underneath there etc and maybe the beam too. Redoxide seems to be the done thing so will be using some of that.

 

Thanks

Red oxide or any other metal primer applied to clean metal does rust protecting fine.

 

However, as boot floor is exposed to road dirt, stonechips etc. you need to protect the primer coating by applying a coat of body protectant atop of it. Which protectant will you choose depends on depth of your wallet, even the cheapest is better than none.

 

For example, I treated the whole underside with Teroson Terotex underbody coating.

Also I filled cavities and closed profiles with Teroson Terotex HV-350 cavity wax, chosen for integrated anti-corrosion additives formula.

 

Brush does the underside appliance job, but no contest to air-gun.
