Home made Waxoil

Not mine i have just nicked it, thought i would stick it here as it looks useful and informative, you could probably make your own version with old engine oil?

 WAX OIL HOMEBREW
 Introduction – This describes how to make your own Wax oil, it’s a home brew that I think works better than the shop stuff, you know the type, black or clear sold in Halfords and the like;
 £20 for 5 litres. My stuff can be made from common or garden ingredients, can be easily sprayed with a 99p leaf sprayer from garden centres and will set into a gel.
 When the weather is about 10 –15 °C is the best temperature to spray it and will form a runny jelly like covering that eeks it’s way into gaps, when things get hotter about 25°C it will go softer and continue to creep in to all the places you want it to and finally in the winter it will go quite ridged and resist all that horrible stuff winter can throw up. The commercial stuff; I’ve found, sprays on and sets after a year and is quite thick, doesn’t creep into the gaps and cracks when it gets old.
 The Ingredients – You will need: -
 
• An old oil container to store it in.
 • 2 Kg of the cheapest candles you can get (Wilko or Lidls etc)
 • 2 Litres of White sprit
 • 0.5 Litres of paraffin oil (the stuff that goes into these little ornamental oil lamps). Very
 cheap engine oil can be used, the cheaper the better as it will have less additives in it.
 The Recipe - Break the candles up into the smallest bits you can and then tip them into the white sprit, put the cap on and put it in the airing cupboard, or somewhere where the temperature will stay around 25°C. These will slowly dissolve over a period of about 2 weeks and it helps to give the mix a good shake every day or so.
 After two weeks most of the candles will have gone into the white spirit and will leave it a thicker milky colour. Now tip the paraffin oil (or engine oil) into your container followed by the liquid part of the white spirit/candle mix; keep the solids out or it will block your sprayer when you use it.
 That’s it, just spray away and it should cost you about £2 for 5 litres, to make more just adjust the volumes, but keep the ratios the same.
 The Application - Warm up the mix so any wax that came out of solution will re-dissolve,
 then direct the sprayer into the gaps, voids or surfaces. It will form a gel when it hits the
 bodywork but it will creep and once the temperature rises a little this will run and creep
 everywhere. It is especially good in panels like bonnets, doors and boots, you can see the stuff running along and filling the seams.
 The Theory - The white sprit has leeching properties, in other words it will creep over any surface it touches, it will not bead like water on a ducks back. The white sprit will creep into gaps and seams and carry the dissolved wax and oil with it, over about a week the white sprit will evaporate leaving behind the wax which will now be solidifying, it will not harden back into candle form because the paraffin oil (engine oil) will keep it liquid, although a thick liquid. If the mix is damaged by say a stone thrown up, then the mix will continue to creep and cover up the hole left by the stone impact.

That solution...I like. The addition of wax makes top sense.
I've usually just mixed old engine/gear/whatever oils and sprayed that in to the chassis.
Thing is, Killer, how long would/ does it last under the bonnet you mention? Does it not just obey Newton and drop on your engine unde the heat of it?

Thing is it is not mine, i just nicked from the Mig welding forum so i have no in depth knowledge of the recipie, I know a few people who use old engine oil so thought the addition of the wax to this kind of makes sense, and has to be better than just the oil.

I can imagine in an engine bay it will become runny again, but that may not be a bad thing.

Also interesting to read about thinning with white spirit to make it easier to spray through a "cavity probe" and the fact the white spirit evaporates away leaving the sticky residue behind, i will be doing this shortly.

on a related note, I was told to use motorcycle chain oil as a protector for the leaf springs, it apparently works its way into the springs as good as anything.

Chain oil lubricates the springs beautifully. However it eats spring eye bushes. I wouldn't recommend it for that reason.

Has anyone found a sprayer (air line driven) which can handle a long probe (chassis length)?

I use a Schultz gun, refilling the original cartridges with a mixture of Waxoyl or Tetroseal, or even Schultz!  (basically whatever I've got in the shed from years ago) and old engine oil, and thinned with white spirit if needed. However, as it is a venturi gun (the air blows over the top of the tube to draw up the mixture), if you try to extend the short tube it blows the air into the canister and you get the mixture coming out of the breather in the gun, all over your hand   :haha:

I understand there are other guns which compress the canister and force the fluid out of the nozzle - that's what I think I need, then I can push the probe in at the back, all the way to the front; pull the trigger and walk slowly backwards.
Much easier and probably more effective than pushing the short pipe into holes along the chassis rails.

So, does anyone have a gun that can do that?

Cheers,
Robin.

Not air line driven, but I was thinking about adapting a weed killer sprayer that you pump up.
My other car is an Allegro

Robin Could you try remove the pick up pipe and use the gun upside down so it gravity feeds?

thanks for that advice, I will use alternative products.

 I too use a Schultz gun. (Or did until last year!)  I found it beneficial to enlarge the breather hole by drilling it out. Without this mod high pressure was prone to collapsing the can and splitting the seem...  Obviously the enlarged breather makes inverted use a bit of a no no. The other important factor is to have the mixture (standard waxoyl) good and hot-the waxoyl can stood in boiling water for a while turns a solid can extremely runny, which, when blasted reaches a good long way.

another tip check the nozzle is clear from the last use before starting, otherwise there is a chance the seam on the can will burst emptying a litre of thick black underseal in your face :haha:

Just done this so have another few tips, as mentioned by Robin if you extend the nozzle on the Shultz gun too far it just blows out of the Nozzle, I learnt the following, (i was using standard Waxoyl not this mix)

1. Heat the can up in the sink with boiling water it needs to be really hot and then it goes like water, I boiled the Kettle on every refil to keep it really hot.
2. Do it on a hot day if possible so it stays runny longer.
3. Don't fill the Shultz can to the top it spray out of the breather hole in to your eyes, 3/4 seems about right.
4. Drape a rag over the brether in the top of the gun stops you getting it in your eyes ;-).
5. The maximum i could extend the pipe (using a shultz gun) was about 500-600mm
6. When you get to the bottom of the can keep going until you have exhausted the wax so you are blowing just air through the nozzle/tube, this clears the nozzle/tube so the wax does not set solid in it whilst you refil.
7. Check you have enough holes to reach all the insides of the chassis with  a short tube before you start.
8. Wear overalls and cover your drive your going to get blathered.
9. Thinning with white spirit does help when spraying.
10. I used about 50 PSI

Mostly common sense but it might save somebody some grief learning it the hard way.

Can I add to that list please? WEAR A GOOD QUALITY FACE MASK!!! Wax oiling the interior of your lungs is not a good idea. When the mix is good and hot, and the pressure is high, the mist gets everywhere...

I might give this a try, got to clean my chassis and re paint, this might be good for coating the inside.
