I went in search of cavity wax today but came home empty. Where do you get this stuff?

Also - is fish oil fish oil, or are there good and bad products?

I want to sort a few potential rust spots and cavities in the soft top, especially in the tray area of my Sierra where I found the rust before. Just wondering is fish oil, cavity wax, or lanolin the best option... and is there any real difference between them - i mean, they're all designed as a preventative and not a cure, but my car's neat enough where I don't have to resort to POR15 just yet.

Which do you guys use?

Did you check your ears?

Sorry had to be said that's the first thing I thought of when I read cavity wax!

Wouldn't you be better off with either rust converter or proper repair and rust preventative paint?

i bought cavity wax from autobarn awhile ago so they should still have it there

my brother years ago, went to some mob in brissy that fill the chassis rails with cavity wax and other common rust areas, they have a database with an insurance mob and could see the common areas each model of 4wd would get rust and concentrate on those areas, cost him $800 and he drove it on the beach every weekend to go to his hang gliding spot, sold it many years later rust free, not sure who does it though.

Cavity wax itself isn't a rust proofing solution.
It should be used over the top of whatever you use for rustproofing, to seal it up.

I buy mine from Supercrap.

I've pulled each panel and rustproofed my car from top to bottom and it's now top coated in camo green, but prevention is better than cure. I just want something to squirt inside the doors and into the unreachable bits i can't access... to be sure, to be sure.

Cavity wax seems pretty hard to track down here in the west. Been to a couple of SCAs, Repco, Bunnings and none stock it.

ERPS have a good cavity spray. I'm sure it would be a rebrand of something else though.
I've used fish oil, cavity wax, and lanolin. I like lanolin the best.
Some brands of cavity wax dry thin and scratch easy.
Fish oil stinks, even the deodorised ones.

Damn cavity wax just sounds to much like a personal lube to be using in the fourby...

Lanolin is great stuff & should be pretty damn good.

Bunnings do something by penetrol? I think. I've used that it seamed pretty good. Its meant to spread into hard to reach places

I have used this product on my cars.
