    Rustproof the inside of the main Chassis tube

    I want to rustproof the *inside* of the main chassis tube,
    including the Napoleon's hat, bottom corners of frame head, rear forks, etc.


    I'm thinking that I will 'proof the bottom ~inch of the tube by pouring a full can of Waxoyl
    (or something else?) into the tube, ensuring it travels into every nook and cranny across the floor of the tube, then draining out the excess through the 2 bolt holes in the frame forks at the rear of the chassis.

    Any thoughts or better ideas?

    I'll be interested to see what you come up with. I had asked Flatlands to do something similar on mine, but they were reluctant as it would make their workspace messy with gooey stuff dripping out everywhere.

    I think you can get the waxoyl with a spray attachment; that's what I did mine with all along the tunnel.

    I also drilled a small hole at the top of the front towers and sprayed into there until it dripped out the bottom drain hole and then fitted a rubber plug into the drilled hole.

    Nothing worse than having things rust from the inside out! `¬)

    (you need to put the waxoyl container into a bucket of warm water, otherwise it is too thick to apply)

    I did this before I fitted my floor pans Steve. I sprayed rust converter inside using a hand pressurised sprayer (the sort you use for weed killer). Main thing is to spray lots in, rotate the tunnel and be able ideally to stand it up on its horns. You can find the pics etc in my thread at http://www.euro-nova.co.uk/vb/showth...ebuild!/page18

    Good info there thanks gents.
    I don't want to use the 360 degree sprayer (that you get with a Waxoyl kit), I can't give a good reason why - other than the mess on the electrical cables, brake cables, gearshift rod, etc. that are sitting in the tube.

    I'd rather just do the bottom inch of the tube floor and sidewalls, then stand the chassis on its end (as in your pic Alistair) and let it drain out of the forks for 24 hrs.

    Is Waxoyl still the best stuff to use?

    I did use the 360 sprayer myself on the buggy tunnel and also the Nova. I figured it can’t hurt to coat everything. Just kept a tray under the drain hole for a few days to collect any initial seepage.

    I found it worked best putting the tin in a bucket of hot water.

    We actually used the process as an article in CKC a few years back
    All the best,

    Steve (and anyone else considering taking this very sensible precautionary measure when they are still in a position to stand the chassis on its horns to drain out the waxoyl, rust converter or whatever they choose),

    Be sure to thoroughly grease the threaded sockets at the ends of the horns, otherwise you'll find it difficult to get the large bolts fully screwed home when you come to fit the transaxle.

    .... just ask me how I know!

    I have just ordered an endoscope, lets see what that shows on mine.
