Waxoyled the Underside of the G500
A job i carry out to all of my cars on a regular basis.
First time is always pretty long winded as need to first thoroughtly clean underside.
I normally use soap and a jet wash and clean as much as possible whilst car is still on ground.
Then ill leave to dry and then ill remove all the covers, i.e. wheel arch liners, sill protectors etc... Also remove as many grommets as I can find. Clean all the exposed areas with wire brush and also a rotating drill attachment to remove all flaky rust.
On this car it took me hours to remove all the mud and general crud from all of the underside... to be expected of a 4x4 though.
Then its the time to get dirty... I use compressed air with a Sealey Gun... I have a flexible lance for all the hollow sections.
Now I dont want to start a debate on the best product to use... Many use Bilt & Hamber, some like Dinitrol... Ive tried them all and always come back to good old Waxoyl.
To be fair, You should use different products for different areas of the car... Some set solid for exposed areas whereas others remain viscous to flow into the crevices of hollow sections. Thats if you want to do the job once only... I prefer to do this once every 3-4 years depending on how heavily the car is used and so I have found Waxoyl is the single best all round product.
I warm the wax in a bucket of boiling water for 10-15 mins to make it nice and thin... Some mix it with thinners but I dont like to do that.
I cover the whole car in plastic bodyshop sheeting. I normally remove the wheels too but in this case it was easier to simply wrap them in plastic as there is great access just by jacking the car up to do the wheel arches.
I have access to ramps here at work which makes this job a LOT easier.
Dont worry the stuff on the exhaust will simply melt off first time car is run...
A very satisfying job... Only thing is I couldnt find many bungs to allow access to inject the main longitudinal chassis tubes... Im sure they must have some kind of protection from factory though...
Hi jay
Don't worry too much about the inner chassis as they are submerged in wax at the factory prior to assembly. If you look at one of Axles posts where hes cut the chassis he shows a picture of the inner section and makes reference to the wax. The wax treatment is also highlighted on a promotional video of the truck being assembled.
Which Sealey gun and lance do you use, as I am planning on doing the same to my truck?

its worth doing did mine in black waxoyl a couple of years ago, due another one
How many litres of Waxoyl did you use?
I used one full 5 litre tin of black tetrosyl plus two 1 litre tins
mines a swb
You can use less if you thin it with white spirit. Maybe upto 50% works well. An no need to go on too thick. A little goes a long way. I've also had really good results using Jotamastic chassis paint. It matches the grey chassis colour quite well. Not perfect but not solid black either.
I used almost two full tins.. 10L.. Although I think when I do it again it will only be around 5L as I wont need to do hollow or non exposed sections again. Its mainly wheel arches and sills that take the brunt.
This is the gun I used, mine came with the flexible lance.
