Rust Proofing Ma Belly!

[Azza]

I'd like to do a bit of rust proofing to the underside of my truck, i've heard that Fishoilene works well to prevent rust, apparantly you can even drive in salt water on a regular basis and still have no problems.... but I also heard that if you use it your vehicle tends to smell like fish

Has anyone here used it? Does it really work as well as the all the hype i've heard about it? and just how bad is the smell?

I think i remember reading somewhere on the pouck.co.uk site that they commonly use a some kind of bitumen sealant. cheap but im guessing it would be messy

Fishoilene is the stuff!

What is does is put a film of oil over the area which any oil would do but then it sets firm.

I used it when I rebuilt a classic car, put it inside all the body cavities and up inside the chassis (used the kero-cleaning gun on the compressor to apply).

When I put it in I stunk of fish, and so did the shed and car. I left all the doors etc open and let it sit for a few days for excess to drip off and then wiped up. Once it sets the smell is gone. You would only pick it if you stuck your nose up to it.

Also dip you bolts in it before fitting them and easily undo them years later.

While I used that in rust prone places, I didn't use it for the underside. It may well work there not sure. But I got a more modern version of the old underseal and thinned it (with petrol) and sprayed it all on the underside.

The good thing about underseal is that it stays soft so stones will bounce off it rather than chip it, but the problem with underseal is that it will eventually crack and peel and the muck etc will get under the lifted bit and be a great rust causer. Hence why I thinned it and sprayed it on, then the petrol evaporates and you are left with a thin skim which will still bounce a stone off but not too thick that it will crack (well it hasn't yet 3 odd years later). and you can paint over this stuff so it cleans easier.

As Fweddy states it is only when it is wet or very hot that it smells and if in the GGE it can get a bit wiffy. I am not sure how it would hold up near the exhaust we used it in and through a boat.

yes true - lovely hot sunny day, picnic out with the classic and things get a little fishy

but you don't mind the smell when you have taught yourself that that smell means preservation of body panels and chassis structure, reminds you of hard work passed and many memories!

Memories of Who? Where and What hard work?
Oh you ment fishing sorry I thought we were getting off topic!

I think as a daily driver I would not use it around the exhaust

I've been doing a bit of reading on it... seems they recommend it for mufflers and it will withstand temps up to 100 degrees

[Steve_t647]

Your exhaust can get a lot warmer than 100deg my race car the headers glowed red hot in the dark! and the muffler was well over 100 deg and this was Petrol (needed to make it richer to keep it below 180).

Diesel burns efficiently with exhaust temperature of approximately 350°C, this would mean the muffler would get up to the 200's, I wonder if this is why some of the exhausts have that weird smell I thought it was just the cat.

I would of thought they get hotter than 100deg too.... but here it is in black and white direct from the manufacturer website;

I guess I could always avoid my exhaust when spraying it on...

[rangimotors]

it'll probably get hot enough to stink but not hot enough to burn off

I think they call that irony, don't they?

[rowinz]

I used fisholene on some rust repairs a while back, sprayed it on with air engine-degreaser gun. It did stink for a week or so. I also got pretty liberal on underside, including the exhaust at the rear. I didn't check heat usage. It peeled/flaked off after a while, but didn't really stink. That was directly on the exhaust, the adjacent bits were all fine.

Use Cavity Wax, fisholene is well out dated.

No fishy smell, easier to apply, doesn't melt in the sun, works better and lasts longer

[MudBum]

Ditto what DB says,cavity wax is the shit.You can get no smell fishoil these days but its not as good as the smelly stuff. Azza go see the boys at Patterson Panel supplies in St Asaph St,ask to see Reg and tell him I sent you. Stonechip protector is awesome to paint ya chassis rails with,really hard and takes a good knock.

So, just what is cavity wax?.... do you spray it on like fishoilene? or is it more like hair gel sounds like it could be messy to apply

[robstroop]

I took off my window wiper motor and sprayed fisholene in the cavity below the windscreen, then realised the fan pulls air from here for heater!! didnt use heater for three days!! but now i know it wont rust around the inlets like so many older cars do and leak water in!!
