Rust proofing S13

[s13q]

Hello,

I own a 96 180sx and would to go about rust proofing the chassis and the chassis rails.

I was thinking going mad with some fish oil and getting it everywhere I can and treating the rails with rust preventing spray.

Im just not sure what exactly to treat them with, product wise.

Anyone experienced in this field?

I live in Sydney, Aus and not next to the sea. We dont get any snow here so rust isnt a major issue. Most S chassis's here dont really rust out with minor care but I would like to do it anyways, especially since I scrape every now and then which may invite rust into the rails.

Fish oil lol , might be better to use something actually meant to rustproof a car . You get a wire brush w/ grinder and buff the entire underneath of the car . You can do this better with the subframe/ tank removed. Then you spray the thing with undercoating. The 3m stuff that comes in spray cans is super easy, but one thing I dislike about it, is it seems to just liquefy and come off if you somehow get gas on it. You might try some actual spray gun undercoating for more durable results

eastwood makes some stuff also. I used it in my engine bay. bought a pint and applied it with a paint brush. it applies thin, and I put a lot of coats. its been 8 months, through a New York winter, and so far it's fine.

Like you said "going mad" with rust-proofing oil is an easy and effective solution. Look for Crown T40 or Rust Check in spray cans. They are the right type of oil and meant to be used by someone in their home garage. Put the car on 4 jack-stands and spray the stuff everywhere you can, especially the holes in the rails to coat them from the inside and displace any moisture.

As mentioned above, you can look for a commercial sized container of rust-proofing oil and apply it with the special spray gun. You'd probably need access to a lift for this method, as you'd be spraying a much higher volume of the oil compared to spray cans and wouldn't make for a safe environment working on jack-stands.

Do they have rust-proofing businesses in Australia? They're quite common here in Canada and I'm sure the US. Probably the easiest method is to take your car there but I'm certain they'd never do as good a job as you would on your own. I'd love for them to give me access to their equipment and I pay for the shop time and material. Perhaps you can offer the guy doing it a cash tip or offer to pay double for them to spend twice as much time and product on it.

Rhino liner or Lizard Skin. Por-15 is very quality shit as well.

If you would rather go for an aerosol type, get the duplicolor bed armor. I did the whole underside of my s13 with it and couldn't be happier. Dries to a nice hard shell unlike a lot of other aerosols.

por-15 like others have said or a lot of people up here in the northeast use fluid film and it seems to work well although i have no firsthand experience with it
