Rust proofing for inside the chassis box sections
PuppiesBalls - 15/2/10 at 07:38 PM

Evening gents,

I have some water in one of the chassis members & im looking for some advise about what i can use to seal it all up to prevent rusting from the inside out.

The member is quite long so i was thinking about using something like expanding foam but then i 'could' end up locking in water

Any ideas gents

You can buy plastic end caps to fit most sizes of box. You really ought to get the water out as much as possible and then waxoyl inside the chassis before fitting end caps though. Dont forget that drilling into chassis members can allow waxoyl out / water in so closed rivets arent a bad idea and waxoyl applied after panelling

caps

Cheers gents, Just purchased that gun, just about to buy a 5 ltr tin of waxoyl, what do you think black or clear ?

Black or clear ?

If it's inside the tubes whichever is the cheaper !

dito, but I would go for clear so you can use it on the outside of the tubes as well (apply with a rag..).. At least that's what I do.

Some people say that you should just close the ends of the tubes off (via welding) so the water can't get in in the first place... On the MK indy chassis only the bottom rail is open at the back, so I will wax inside there, I guess this is to allow the water out...
