    Rustproofing

    Im going over to fraser again soon, so i pulled the factory bashplates off my FJ in preparation for a ARB set i have coming, and on top of the bash plates is all rusty, and not just surface rush but big flakes. It looks like its just just starting to come up onto the cross member, not bad, but naturally I wanna jump on it.

    So i found a local mob who does rust proofing. They showed me the product and it looks like a tar sorta epoxy sort of deal, they say it will never come off even if sand blasted etc.

    So my plan is leave the bash plates off, bin them, clean and rust proof the underside and under where the bashplates go, then fit up the ARB stuff over the top.

    Does this sound like a solid plan or does anyone have any better ideas?

    If you put that heavy tar stuff on - just make sure EVERYWHERE underneath where it covers is bone dry. If it's got any moisture at all, it will be trapped under the tar covering..

    yep, toss the factory flimsy ones and clean it all and let it dry out for as long as possible before getting the coating.. make sure you put ALL your bash plate mounting bolts back into their threads BEFORE they spray the tar on or you will have them fill the holes with that shit and it will never come out...

    Once over on Fraser - just try and keep out of the salt water as much as possible - I know it's not always possible when crossing @ Eli Creek etc - but try and minimise it as much as possible and pick the shallow bits and don;t then go screaming off into the sand flicking it up when underneath is all wet and get a heap of sand stuck under the body and in chassis rails etc. When you get back off the island - head to the under body wash and take a good amount of time to get into all the little hidey holes etc and flush out all the sand etc with fresh water...

    Paint it with por15? They have a few different options but it would look better than that tar shit.

    It self levels etc

    Eli creek is fresh water.

    The question i have about the tar shit is what about inside the rails? How do they get it inside there? I've heard of people using fish oil, but not too sure i want to be smelling like a mermaids arsehole all the time while driving.

    Yeah i spend about a month (combined) a year on fraser, i know how to drive it and i stay out of salt water, but, the salt and the sand still gets everywhere.

    I'd buy a new FJ if they still made them, but they dont so i'll keep going with this one another couple of years and see if anyone releases any new interesting 4x4's that dont look like a refrigerator.

    thats a pro tip about putting the bolts back in the holes before they rust proof tho southo, thanks for that.

    They do an odourless fish oil for rust proofing. There's also a Wurth product that's supposed to be good, and poms have raved about "Waxoyl" since the dawn of time...

    What’s the tar stuff? The “it can’t be sand blasted off” comment is total BS my old man is doing a coating atm which is the strongest industrial coating you can get and even that lifts at 175psi.

    There’s a few different types of coating out there I know a guy that does a polyethylene which is strong then there’s polyurea which is even stronger.

    Assuming that "tar stuff" does not set hard it would be a cunt to sandblast off, if at all.

    Nope my old man has had sand blasters come and clean actual waterproofing tar off concrete and it works fine only drawback it destroyed the concrete so it was not fit for the job.

    I already clean, rust remove and fish oil under the car about once a year after my season of trips over there. you can buy fish oil in a can from supershit for like $2

    Anything on the beach at fraser your going to get salt, and yes Eli can be very wide and salty depending on conditions. its really bad right now actually, i'll see if can find a video

    it feels like a tar/rubber epoxy, you can push into it with your finger and it bends in and slowly extends out.

    Actually it kinda reminds me of the really thin dynamatt sound deadening stuff we used to use back in my doof doof days.

    i'll get pics tomorrow

    Heres a video of me crossing Eli a couple of weeks back at mid tide. As you can see theres no way your not getting a salt bath doing it at the moment.

    downey st rustproofing does a good job. i spent 2wks on fraser over christmas and then spent a couple of hours at home with the hose cleaning out all the sand, which gave me a lot of time to admire their handiwork. not cheap ($700 odd) but i think it's worth it. they also do an after beach wash for about $80. seems like a lot of money, but it took me more than 3hrs to clean the car and about $15 worth of water.

    If some one had a big concrete bath for 4x4's could you drive in and dilute the salt to an extent that it minimises rust? Like a ramp going down into a big long pool you drive through at 5kmh and get to the ramp at the other side and drive out and there would be a big balance tank with a massive filter system.

    Something like that would be useless here in Canberra because cars don't really rust here but would it be a money maker in QLD? I mean every man and his dog are building car washes.

    We used to run through a creek near our house after beach trips, followed by a good few hours with karcher, hose and sprinklers.

    Problem is R man is the sand and salt get everywhere, chassis rails, shock towers, above fuel tanks etc. you’ll never get it perfect but it all helps
