No-Mar sells a vegetable (soy) oil based goo that's extremely slick and snotty. I wonder if emulsifying soy oil and water in a blender would be a good place to start.
Sounds feasible, and worth looking into.
Its not like you or should i say I/ Me, i dont use lots of it and i suppose a tub if you seal it up lasts a good wile for just the family tyre consumption, but in the uk at the moment there is not a lot of profit in tyres and tyre fitting, so firms charge in some instances double for a tyre what you could buy online , and then the dismount of the old tyre mounting and balancing. this boosts their income and the consumer carries the financial hit, and in my opinion inappropriately so.
What has sparked my interest in this is a recent sittuation where i needed four tyres fitted which i had in hand used. the average price was £15 a wheel unbalanced, and quite a few were £18 a wheel unballanced. And £30 for a part warn tyre fitted again unbalanced, when i could buy new tyre to my door for £42 including vat.
I have basic bar and post type gear, but imediately went out and bought a used but vgc turntable machine for £300.
Its drastic move i know but needs must and one tyre firms boss has his wife working in the office and she drives a 2021 aston martin, so couple this with his supercharged new defender and new hylux mobile tyre service truck unit and the manager in a 2022 ranger. some one is making some money someplace.
I am fitting my own in future period, and i just did not like the look of the price of euro paste thats all.
