    You've already used one, it can be rubber, steel, wooden, a softer copper head etc etc just pick something suitable for the job in hand

    Acetone and ATF do not mix regardless how much you shake or agitate. They are incompatible fluids just like oil and water.

    Above is a 50-50% "mix" of used ATF transmission fluid drained from my Smart 450 and industrial acetone. I've been shaking the jar now for at least ten years and the fluids have still not mixed.
    The fluids will separate in less than 5 minutes after having shaken jar vigorously.
    They do not need to mix. The volatile solution penetrates then evaporates leaving the lubricant. It will work with any pair of suitable liquids.

    Here is a 40% acetone / 60% ATF mix that is at least 2 years since mixed. No separation at all ever.

    I think Tolstoy's concoction is a Ribena mix with undertones of damson jam , this is indefensible.

    Transmission oil gets black after years of service but is still transmission oil.
    Whether fresh or old, ATF and acetone just won't mix. Google it and you will see.


    The acetone evaporates in seconds cooling down the ATF thereby making ATF more viscous and less effective in penetrating crevices.

    That is untrue. It mixes fine.

    Anyway if you use a puller, use the persuader also otherwise the shoes may tilt and make it even worse , a persuader will maybe jog them along as you pull

    If you look closely at my picture you'll see what looks like a sealant oozing from the hub/drum joint.
    At first I thought it was just a build up of rust, but when I tried to clean it off a powdery 'white sealant' was exposed, and this seems to be covering the complete surface between the hub and drum.

    I think I may need to get hold of a puller - if I can find one large enough locally.
