rust prevention products

[cruiser60series]

Got the roof of my troopy so have unique access to the cavity between the skins of the panels.

I want to squirt some sort of goop down there to prevent/delay rust in the future.

Any ideas what product i should try using?

[Wilko76]

fish oil or lanolin in my opinion

lanolin

Would the lanolin flow around in the cavities, or does it need to be applied directly to the surface to protect? (I've never used it before.)

[want33s]

50/50 mix of lanolin and cavity wax.
Cavity wax comes in 4 litre tins like thinners and is available at auto paint suppliers and sometimes at Supercrap.

NOT REAPEAT NOT FISH OIL Just just some rust out of the roof today.
My mate warned me that it stinks. I sprayed it a little and thought thats all right . BUT.......... the smell gets stonger and stronger now the patrol smells like off fish and i sprayed it were i thought it would be right .

Lanoline is ok at least sheep smell better then fish and it's a turn on for new zealanders

the fish oil smell will go away after a few weeks.

you can buy odourless fish oil now too.

whats everyones opion on the electronic rust systems. are they the goods or just a big scam. be good to hear it from someone that has one fitted.

Yep

I used some 'deodourised' fish oil. It smells like fish.


Well, for the first few weeks anyway.

get with the time's fish oil and lanolin are from the dark age's

por15 is THE ONLY way to go for stuff like this providing you can reach something in there to paint it on (brush)

not cheap but you won't find a better product for rust prevention

absolutely no point in using por15 on an old car which has already got rust developing inside it somewhere. and any 4wd which has been used as a 4wd or lived near a coastal area will be oxidising somewhere.


especially if its japanese

Try a search, been well discussed...

but my opinion is the ERPS is doin a fair job on the Sierra. MiL had paint on and an electronic system fitted at a Toyota dealer on her new 100 series, musta hooked it up in reverse coz she had chassis cancer within 3 months, swapped it out for an ERPS and seems to have stopped the spread two years later.

I fit all of those categories panels have a short life on my property

sounds like lanolin and cavity wax will be the go, I'll make some squirty nozzle thing and shoot it down into the panels. Should it take long to dry/set?

The beauty of 50/50 lanolin and cavity wax is that it stays liquid for ever under the skin it forms.
The more liquid it is the better the penetration.
Fill every nook and cranny and leave it alone for a week or two and then go for a long drive on a dusty road. The dust will help to form a skin so no more dribbles. After that, forget all about it for a year and then repeat.

Agreed ... POR15 is the shizz. Have seen it used in numerous industrial applications, including after fire events where the intense heat strips the galv off galvanised steel, and it is pretty impressive. It must be pretty much impermeable as it stops oxidation occuring under the coating, ie if you paint it on a mildly rusted (not scaling) surface it will stop rust there. As you say though, only good for brush on so not feasible where access is difficult.
