Rust prevention in 1990 GQ Patrol

Wash it and clean it before you go, clean up any bare spots etc, when you come home do it all again.
Truck wash or similar works well. Spray it on with a garden spray, leave it for an hour or so and hose it off.
If you want to be really anal a bucket and sponge job with a good quality carwash in warm water would be the go.
tidy up any rust spots etc.

Hi XXXX

We do about a weeks beach work per year, and simply give the Patrol a thorough clean afterwards. The under body wash is a good start, but I prefer to wash under the body myself when I get home. I put the Patrol on ramps and get underneath and wash everywhere I can reach, including flooding the chassis rails etc......., top of tanks, top of running gear, diffs, gearbox and t/case etc, till clean water is running off everywhere, not sandy coloured sludge. Then it's a matter of checking for any rust spots, rubbing them back and painting with suitable paint. The engine bay gets a good wash as well. Inside the truck, we remove all of the interior to vacuum out the kilo's of sand we have aquired, and check the floor for any rust, which gets rubbed out and painted.

Takes a couple of days all up, but worth the effort!

Hope this helps
Cheers

XXXX,

Ditto to what Brian said.

We are in amongst the sand and salt water every few weeks as my outlaws live at Rainbow Beach and we also do a few Moreton, Fraser and Straddie trips as well each year.

We don't do the underbody wash any longer near the beach but we do the rest like Brian does.

In addition to that I have fitted an electronic rust prevention system which to date seems to work well. IMO a lot of the pros and cons are like the old chetsnuts about fridge brands and vehicle brands and I haven't got a really clear picture of which method may be better than the other but whichever way you go I think they are a benefit but not the complete answer to the problem.

You have to be pretty meticulous wiith the maintenance as the salty conditions can damage you car if not careful.

Biggest problem for a lot of people nowadays is that you can't use the hose at home to clean your car. In Brisbane we are on level four and due to go to level 5 water restrictions in April so that is a problem. I ended up installing a decent size water tank and pump so that we can still keep the cars clean and gardens watered etc. Slightly off topic but water tank sales are huge here at present with some companies quoting a wait time of several months to supply one.

Anyway hope you get it sorted.
