Rust Proofing and Chassis Protection

(1/2) > >>

Muck:
Having just shelled out for welding on my rear cross member I want to make sure the full chassis on my 1988 RRC gets some TLC this year. Anyone got any special hints or tips and preferred treatment for protecting the chassis - Waxoyl, Hammerite , rust killer etc??

I don't fancy shelling out for a Before N After Treatment!!

Jonny Boaterboy:
Rust is my mosted hated enemy  :twisted: I do anything and every this to slow it down. The best and most cost effective way I have found it to use 50/50 wax oil (hamerite, comes in yellow 5 litre tins) and old engine oil stored up from all the engine oil changes a V8 loves. do it in the summer as if its cold you will strugle to get the wax oil to flow, heat the wax oil and old engine oil useing a blow fan heater, the hotter the better mix together, and spray using a spray gun with compessor, or if you don't have a compessor the hand pump spray kits that Waxoil make work quite well. make sure you jet wash off the underside first and spray in all available in the chassie useing an exstesion pipe to reach further. dont worry too much about geting it on the exhast as it will burn off when you start it up (very smokey for the first 5 mins do not drive till all has burnt off on tickover) Cover all brake and air surspension bags using masking tape and news paper.

Its a dirty smelly job but Your Range Rover will love you for it I tend to do mine once a year and have no weld scars yet!

Zinc, Zinc, and more Zinc.

Galvanising is best but not practical for a repair; you can get high zinc paint to slap on, the more of that the better. You can do that then Waxoyl or whatever you prefer but the more zinc there is the longer it will last.

As for using Engine Oil it gets very questionable; if you go through a ford and get the oil in the water course it's not good.

Jonny Boaterboy:
Thats a very good point about the oil coming off in water, I have noticed it when washing off the underside on my drive but it has got less, to the point where it is hardly noticable..... but that means I have been washing it off down drains up untill now. The only reason old engine oil was used was to cut down the cost of buying waxoil so probable best to just stick with wax oil.

Sorry for poluting will switch back to just wax oil as well, not so bad when oil runs onto my own drive and into my own soackaways but not aceptable in streams puddles etc on green lanes.

electricbluebadger:
I would steer clear of hammerite from personal experience.... bad idea round here as the flint / gravel has a tendency to chip it off leaving small areas where water can then creep and do even more damage.....

Try here...
