rust protection

[JEWIENEWIE]

thinking about spraying the underbody of my troopywith something to help protect from rust. I do a bit of beach driving and would like to do something to it now to slow down protect it. Have a compressor and spray gun, any ideas?

Go grab your self some Tectyl 506. It comes in spray cans or in tins you can pour into your spray gun.

Don't worry about it before trip. Come home give it a good wash then spray. {fisholine} DO this as much as you like between trips. Have heard of spraying with a sumpoil & diesel mix then drive over a dusty road to give it a protective layer before trip.

Biff, why shouldnt i spray before i go?Will the sand stick to the fisholine and be permanatly stuck there? Is fisholine better than tectyl

Any other ideas?

I find the fish oil type stuff to always stay sticky where as the Tectyl stuff goes hard like wax.

go tectyl, cant' be beaten, it actually crawls into nooks and cranny's

Jewienewie Not saying one is better the other. All I am trying to get across is after a beach trip nothing beats a good under body wash. What I do is I'll will wash the under body at least three times, untill sand isn't coming out from the under body. Don't be afraid to get under there. I do this over a week allowing sands to dry and to be dislogde by driving. I've found one wash isn't enough, You should see the sand that comes out at each wash, as build up of sands in your chassie is no good. For eg: I know of Nissans with front end coil suspension, that have a cover plate over the top of the shockie bolt, here a mate didn't check under that cover, and the shockie fell from the bolting point due to sand build up creating moisture that rusted the bolting mount. So those who have Nissans, be sure to check under these plates! My mate keeps them off.

As for not spraying your car before your trip, keeping up the fisholine between trips or whatever rust proofing you prefer will make it ready for future trips.

I've had proffessonal rust proofing under the carriage over the yrs, and found that this type of rust proofing is ok for the beach but if you want to get off road and find the gravel, stones can damage and chip this rust proofing away.

I find that people tend to get over confident with professional rust proofing, but this is not the case - you should always be dilligent. Get it before it gets you.

I find this works for me and hope it can be of use to you.

always go electronic as a back up also,,, i dont spray with anything other than water under body,,, and after a beach trip the old gerni is still used a week later just to make sure,,,some 4bies have probs with oil based sprays getting behind seals, thus in turn when dry the old creak and squeak noise starts to appear,,, not to mention (as previously stated) sand becoming glued in spots,,,i use good old elbow grease and electronic on mine,,, never had any dramas,,,, by the way the electronic units are transferable from 1 truck to another,,,

I've seen electric rust protection systems that work so well as to rust out in the very spot that the unit is mounted. Have never been game to try it on my own 4b's for this reason. :-/

[choppa]

earlier versions of electronic units alymar were subject to this problem due to the fact they were bolted or screw on applications,,,now there self adhesive

the more expensive the better the unit,, seems to be the go as well,,,

i work within an industry that sees an average of 150 units per month sold,,, and the warranty (which is another benefit opposed to spray on) claims are very rare

i'll have a chat to the dept in charge of em,,,and if any interest i'll see what i can acquire them for at a cost to members if theres any interest,,,,

just in further defence,,, the units i refer to, have a LIFETIME, 100% guarentee
i have been associated with,, and have a unit installed and transferred to my various wheels over the past 11years,,,,,,never had a prob,,,,,

[choppa]

as a footnote to above reply,,, the reason they rusted was due to the holes drilled to mount the units were seldom sealed,, and in some units you were recommended to scrape the surface back to bare metal to ensure proper contact,,, sealant was not mentione after installation procedure and of course the enivatable happens,,,

this is one concern over srayon applications,,, if water does come between the body and the sealant,, especially if any chips or scratches occur after applying,,, you physically cant see the rust occuring,,,so early prevention to stop the cancer is limited,,,, you generally find out after you put your foot through the floor

I live at Teewah on Noosa North Shore and drive beach most days of the year. Washing the vehicle each day is not practical as is going to be covered again next morning. Have used Ensis fluid from Shell for past 20 years and results speak for themselves. Have hilux that lives on the beach with 340000 km on the clock and no rust issues. Just need to respray every 6 months or so. Combined with turtle wax polish for paintwork and thorough hose after beach, irregular beach goers should never have rust probs. Electronic units have caused many probs here when people have relied entirely on them. Would suggest using them in conjunction with spray just in case they do work.

[JEWIENEWIE]

Slider, how do you apply the fluid. Underbody? Whole vehicle? Can it be put through a spray gun? Thanks mate,
Jewienewie

[Slider]

Jewienewie, the ensis can be applied through a spray gun. There are a few types of ensis available. I generally mix SDC (fine liquid) with V (thicker) so as to get fluid to run and coat although I think the V on its own would work well with SDC no longer available. Shell have replaced the SDC with a newer safer product but I haven't had to purchase yet. Have found to use fine fluid on its own causes too much vapour and drip and coverage rates are not as good as mixing with the V (50/50)
I spray everything underneath that can rust including the exhaust. Usually polish overspray off paintwork afterwards although won't adversely affect the paint.
SDC is similar viscocity to sump oil. And V would be more like Tectyl.
Is available from various locations am sure but Bakers Construction & Industrial at Coopers Plains - 33459011 carry the product.
Hope that helps jewienewie.

For my rust protection I have the CouplerTec (Electronic) Heady Duty 4wd system. Look at how many companies/surf life saving use them was enough reassurance for me. (no affiliation) I also sprayed the underside with fish oil, and it has dried fully. I will do this every about 3-6 months. Also a good wash after every trip spending heaps of time under the car. The car is off road every week so basically every weekend it’s getting an underside clean. So basically I've got my fingers in every pie :)
