Anti - corrosion for internal of RHS chassis members?

[stew]

Whats the general consensus?

I was thinking either injecting something like waxoyl into the chassis once finished.

Or expanding foam?

Or is it worth bothering?

I was thinking to avoid any rattles etc from inside the chassis.

What do the likes of caterham/westfield etc do?

Im maybe overthinking, but its a sat night and im stuck in! lol

cheers,

I dont think expanding foam will do anything.
Try something like this;

I doubt if there is anything rattling about in the RHS you will be able to hear it anyway ...pretty loud these cars

Been mentioned before and opinion is that there is very little rust on the inside of the welded tubes as there is no ingress of moisture,a squirt of waxoil or wd40 would not go a miss in the open ends.

there was this stuff called ziebart
seen it on an old mk1 fiesta and a alfasud both spotless in the rust deparment
was like a black waxoil not sure if you can still get it but cars i have seen spoke for themselfs
alfasuds where known for rusting

im going for some form of wax injection on mine

They all look like good ideas but the only way you can be sertain you cover everthing is by galvanising?

Think you will find Ziebart died along with plugs,points and condensers,used to use it on new cars in the 70's.:eek:

Filled the box section chassis of my Land Rover with old engine oil----seemed like good idea til it needed some welding:D

if was good enough to keep the rust buckets from the 70s alive to the 00s even things like fords and alfas that would keep there owners awake at night as thay could hear them rusting apart it must have been good.

most of them cars can only be swept off a workshop floor now:rolleyes:

Worried about Rusting on the Insides of your chassis tube!? You should live so long :rolleyes:
Ziebart was horrid crap, Ugly and overpriced. It 'required' a Semi annual redo to keep it's Warranty active.. as if.

If the tubing is sealed it will not rust - oxidation process (rust) need moisture and most of all oxygen to happens...
